Fix roles parsing in client nodes sniffer (#52888)
We mades roles pluggable, but never updated the client to account for
this. This means that when speaking to a modern cluster, application
logs are spammed with warning messages around unrecognized roles. This
commit addresses this by accounting for the fact that roles can extend
beyond master/data/ingest now.

[ML] Add indices_options to datafeed config and update (#52793) (#52905)
This adds a new configurable field called `indices_options`. This allows users to create or update the indices_options used when a datafeed reads from an index.

This is necessary for the following use cases:
 - Reading from frozen indices
 - Allowing certain indices in multiple index patterns to not exist yet

These index options are available on datafeed creation and update. Users may specify them as URL parameters or within the configuration object.

Adds recall@k metric to rank eval API (#52889)
This change adds the recall@k metric and refactors precision@k to match
the new metric.

Recall@k is an important metric to use for learning to rank (LTR)
use-cases. Candidate generation or first ranking phase ranking functions
are often optimized for high recall, in order to generate as many
relevant candidates in the top-k as possible for a second phase of
ranking. Adding this metric allows tuning that base query for LTR.

[7.x] Smarter copying of the rest specs and tests (#52114) (#52798)
* Smarter copying of the rest specs and tests (#52114)

This PR addresses the unnecessary copying of the rest specs and allows
for better semantics for which specs and tests are copied. By default
the rest specs will get copied if the project applies
`elasticsearch.standalone-rest-test` or `esplugin` and the project
has rest tests or you configure the custom extension `restResources`.

This PR also removes the need for dozens of places where the x-pack
specs were copied by supporting copying of the x-pack rest specs too.

The plugin/task introduced here can also copy the rest tests to the
local project through a similar configuration.

The new plugin/task allows a user to minimize the surface area of
which rest specs are copied. Per project can be configured to include
only a subset of the specs (or tests). Configuring a project to only
copy the specs when actually needed should help with build cache hit
rates since we can better define what is actually in use.
However, project level optimizations for build cache hit rates are
not included with this PR.

Also, with this PR you can no longer use the includePackaged flag on
integTest task.

The following items are included in this PR:
* new plugin: `elasticsearch.rest-resources`
* new tasks: CopyRestApiTask and CopyRestTestsTask - performs the copy
* new extension 'restResources'
```
restResources {
  restApi {
    includeCore 'foo' , 'bar' //will include the core specs that start with foo and bar
    includeXpack 'baz' //will include x-pack specs that start with baz
  }
  restTests {
    includeCore 'foo', 'bar' //will include the core tests that start with foo and bar
    includeXpack 'baz' //will include the x-pack tests that start with baz
  }
}

EQL: Add integration tests harness to test EQL feature parity with original implementation (#52248) (#52675)
The tests use the original test queries from
https://github.com/endgameinc/eql/blob/master/eql/etc/test_queries.toml
for EQL implementation correctness validation.
The file test_queries_unsupported.toml serves as a "blacklist" for the
queries that we do not support. Currently all of the queries are
blacklisted. Over the time the expectation is to eventually have an
empty "blacklist" when all of the queries are fully supported.

The tests use the original test vector from
https://raw.githubusercontent.com/endgameinc/eql/master/eql/etc/test_data.json.

Only one EQL and the response is stubbed for now to match the expected
output from that query. This part would need some tweaking after EQL is
fully wired.

Maria Ralli ba8d6d1fb5 Remove Xlint exclusions from gradle files
Backport of #52542.

This commit is part of issue #40366 to remove disabled Xlint warnings
from gradle files. In particular, it removes the Xlint exclusions from
the following files:

- benchmarks/build.gradle
- client/client-benchmark-noop-api-plugin/build.gradle
- x-pack/qa/rolling-upgrade/build.gradle
- x-pack/qa/third-party/active-directory/build.gradle
- modules/transport-netty4/build.gradle

For the first three files no code adjustments were needed. For
x-pack/qa/third-party/active-directory move the suppression at the code
level. For transport-netty4 replace the variable arguments with
ArrayLists and remove any redundant casts.

[Ml] Validate tree feature index is within range (#52514)
This changes the tree validation code to ensure no node in the tree has a
feature index that is beyond the bounds of the feature_names array.
Specifically this handles the situation where the C++ emits a tree containing
a single node and an empty feature_names list. This is valid tree used to
centre the data in the ensemble but the validation code would reject this
as feature_names is empty. This meant a broken workflow as you cannot GET
the model and PUT it back

Implement top_metrics agg (#51155) (#52366)
The `top_metrics` agg is kind of like `top_hits` but it only works on
doc values so it *should* be faster.

At this point it is fairly limited in that it only supports a single,
numeric sort and a single, numeric metric. And it only fetches the "very
topest" document worth of metric. We plan to support returning a
configurable number of top metrics, requesting more than one metric and
more than one sort. And, eventually, non-numeric sorts and metrics. The
trick is doing those things fairly efficiently.

Jay Modi 3edadfefd0 RestHandlers declare handled routes (#52123)
This commit changes how RestHandlers are registered with the
RestController so that a RestHandler no longer needs to register itself
with the RestController. Instead the RestHandler interface has new
methods which when called provide information about the routes
(method and path combinations) that are handled by the handler
including any deprecated and/or replaced combinations.

This change also makes the publication of RestHandlers safe since they
no longer publish a reference to themselves within their constructors.

endpoint skeleton, for the purpose of starting to build out the build

than commiting a fully-functioning autoscaling API, we introduce here
the skeleton so that we can start wiring up the build and testing
infrastructure, establish security roles/permissions, an so on. This
way, in a forthcoming PR that introduces actual functionality, that PR
will be smaller and have less distractions around that sort of
infrastructure.

Cleanup test user in HLRC test (#49477) (#51942)
SecurityIT.testGetUser creates a user for testing purposes, but did
not delete the user at the end of the test. This could leave the
cluster in an unexpected state for other tests.

This commit:
- Deletes the user at the end of `testGetUser`
- Adds the test-name as metadata to the users that are created in `SecurityIT`
  so that their origin is clear if they do interfere with other tests
- Enables SecurityDocumentationIT.testGetUsers on the expectation that
  the new cleanup step will resolve the unreliability of that test.

Create a class to hold field capabilities for one index. (#51844)
Currently, the same class `FieldCapabilities` is used both to represent the
capabilities for one index, and also the merged capabilities across indices. To
help clarify the logic, this PR proposes to create a separate class
`IndexFieldCapabilities` for the capabilities in one index. The refactor will
also help when adding `source_path` information in #49264, since the merged
source path field will have a different structure from the field for a single index.

Individual changes:
* Add a new class IndexFieldCapabilities.
* Remove extra constructor from FieldCapabilities.
* Combine the add and merge methods in FieldCapabilities.Builder.

Enable tests in FIPS 140 in JDK 11 (#49485)
This change changes the way to run our test suites in 
JVMs configured in FIPS 140 approved mode. It does so by:

- Configuring any given runtime Java in FIPS mode with the bundled
policy and security properties files, setting the system
properties java.security.properties and java.security.policy
with the == operator that overrides the default JVM properties
and policy.

- When runtime java is 11 and higher, using BouncyCastle FIPS 
Cryptographic provider and BCJSSE in FIPS mode. These are 
used as testRuntime dependencies for unit
tests and internal clusters, and copied (relevant jars)
explicitly to the lib directory for testclusters used in REST tests

- When runtime java is 8, using BouncyCastle FIPS 
Cryptographic provider and SunJSSE in FIPS mode. 

Running the tests in FIPS 140 approved mode doesn't require an
additional configuration either in CI workers or locally and is
controlled by specifying -Dtests.fips.enabled=true

Ensure we emit a warning when using the deprecated 'template' field. (#50831)
Since 6.0, the 'template' field has been deprecated in put template requests in
favour of index_patterns. Previously, the PutIndexTemplateRequest would accept
the 'template' field in its 'source' methods and silently convert it to
'index_patterns'. This meant that users specifying 'template' in the source
would not receive a deprecation warning from the server.

This PR makes a small change to no longer silently convert 'template' to
'index_patterns', which ensures that users receive a deprecation warning.

Add per-field metadata. (#50333)
This PR adds per-field metadata that can be set in the mappings and is later
returned by the field capabilities API. This metadata is completely opaque to
Elasticsearch but may be used by tools that index data in Elasticsearch to
communicate metadata about fields with tools that then search this data. A
typical example that has been requested in the past is the ability to attach
a unit to a numeric field.

In order to not bloat the cluster state, Elasticsearch requires that this
metadata be small:
 - keys can't be longer than 20 chars,
 - values can only be numbers or strings of no more than 50 chars - no inner
   arrays or objects,
 - the metadata can't have more than 5 keys in total.

Given that metadata is opaque to Elasticsearch, field capabilities don't try to
do anything smart when merging metadata about multiple indices, the union of
all field metadatas is returned.

Here is how the meta might look like in mappings:

```json
{
  "properties": {
    "latency": {
      "type": "long",
      "meta": {
        "unit": "ms"
      }
    }
  }
}
```

And then in the field capabilities response:

```json
{
  "latency": {
    "long": {
      "searchable": true,
      "aggreggatable": true,
      "meta": {
        "unit": [ "ms" ]
      }
    }
  }
}
```

When there are no conflicts, values are arrays of size 1, but when there are
conflicts, Elasticsearch includes all unique values in this array, without
giving ways to know which index has which metadata value:

```json
{
  "latency": {
    "long": {
      "searchable": true,
      "aggreggatable": true,
      "meta": {
        "unit": [ "ms", "ns" ]
      }
    }
  }

practice we never mutate them after they are built. And we certainly
don't change the static reference. Anyway, this adds `final` to these
parsers.

I found the non-final parsers with this:
```
diff \
  <(find . -type f -name '*.java' -exec grep -iHe 'static.*PARSER\s*=' {} \+ | sort) \
  <(find . -type f -name '*.java' -exec grep -iHe 'static.*final.*PARSER\s*=' {} \+ | sort) \

[7.x][ML] Implement force deleting a data frame analytics job (#50553) (#50589)
Adds a `force` parameter to the delete data frame analytics
request. When `force` is `true`, the action force-stops the
jobs and then proceeds to the deletion. This can be used in
order to delete a non-stopped job with a single request.

Make some ObjectParsers final (#50471) (#50556)

Add remote info to the HLRC (#50483)
The additional change to the original PR (#49657), is that `org.elasticsearch.client.cluster.RemoteConnectionInfo` now parses the initial_connect_timeout field as a string instead of a TimeValue instance.

The reason that this is needed is because that the initial_connect_timeout field in the remote connection api is serialized for human consumption, but not for parsing purposes.
Therefore the HLRC can't parse it correctly (which caused test failures in CI, but not in the PR CI
:( ). The way this field is serialized needs to be changed in the remote connection api, but that is a breaking change. We should wait making this change until rest api versioning is introduced.

[7.x] Add ILM histore store index (#50287) (#50345)
* Add ILM histore store index (#50287)

* Add ILM histore store index

This commit adds an ILM history store that tracks the lifecycle
execution state as an index progresses through its ILM policy. ILM
history documents store output similar to what the ILM explain API
returns.

An example document with ALL fields (not all documents will have all
fields) would look like:

```json
{
  "@timestamp": 1203012389,
  "policy": "my-ilm-policy",
  "index": "index-2019.1.1-000023",
  "index_age":123120,
  "success": true,
  "state": {
    "phase": "warm",
    "action": "allocate",
    "step": "ERROR",
    "failed_step": "update-settings",
    "is_auto-retryable_error": true,
    "creation_date": 12389012039,
    "phase_time": 12908389120,
    "action_time": 1283901209,
    "step_time": 123904107140,
    "phase_definition": "{\"policy\":\"ilm-history-ilm-policy\",\"phase_definition\":{\"min_age\":\"0ms\",\"actions\":{\"rollover\":{\"max_size\":\"50gb\",\"max_age\":\"30d\"}}},\"version\":1,\"modified_date_in_millis\":1576517253463}",
    "step_info": "{... etc step info here as json ...}"
  },
  "error_details": "java.lang.RuntimeException: etc\n\tcaused by:etc etc etc full stacktrace"
}
```

These documents go into the `ilm-history-1-00000N` index to provide an
audit trail of the operations ILM has performed.

This history storage is enabled by default but can be disabled by setting
`index.lifecycle.history_index_enabled` to `false.`

Resolves #49180

* Make ILMHistoryStore.putAsync truly async (#50403)

This moves the `putAsync` method in `ILMHistoryStore` never to block.
Previously due to the way that the `BulkProcessor` works, it was possible
for `BulkProcessor#add` to block executing a bulk request. This was bad
as we may be adding things to the history store in cluster state update
threads.

This also moves the index creation to be done prior to the bulk request
execution, rather than being checked every time an operation was added
to the queue. This lessens the chance of the index being created, then
deleted (by some external force), and then recreated via a bulk indexing
request.

Resolves #50353

Backport remote proxy mode stats and naming (#50402)
* Update remote cluster stats to support simple mode (#49961)

Remote cluster stats API currently only returns useful information if
the strategy in use is the SNIFF mode. This PR modifies the API to
provide relevant information if the user is in the SIMPLE mode. This
information is the configured addresses, max socket connections, and
open socket connections.

* Send hostname in SNI header in simple remote mode (#50247)

Currently an intermediate proxy must route conncctions to the
appropriate remote cluster when using simple mode. This commit offers
a additional mechanism for the proxy to route the connections by
including the hostname in the TLS SNI header.

* Rename the remote connection mode simple to proxy (#50291)

This commit renames the simple connection mode to the proxy connection
mode for remote cluster connections. In order to do this, the mode specific
settings which we namespaced by their mode (ex: sniff.seed and
proxy.addresses) have been reverted.

* Modify proxy mode to support a single address (#50391)

Currently, the remote proxy connection mode uses a list setting for the
proxy address. This commit modifies this so that the setting is
proxy_address and only supports a single remote proxy address.

Adds `GET /_script_language` to support Kibana dynamic scripting

Response contains whether `inline` and/or `stored` scripts are
enabled as determined by the `script.allowed_types` settings.

For each scripting language registered, such as `painless`,
`expression`, `mustache` or custom, available contexts for the language
are included as determined by the `script.allowed_contexts` setting.

Response format:
```

  ],
  "language_contexts": [
    {
      "language": "expression",

Enable simple remote connection strategy (#49561)
This commit back ports three commits related to enabling the simple
connection strategy.

Allow simple connection strategy to be configured (#49066)

Currently the simple connection strategy only exists in the code. It
cannot be configured. This commit moves in the direction of allowing it
to be configured. It introduces settings for the addresses and socket
count. Additionally it introduces new settings for the sniff strategy
so that the more generic number of connections and seed node settings
can be deprecated.

The simple settings are not yet registered as the registration is
dependent on follow-up work to validate the settings.

Ensure at least 1 seed configured in remote test (#49389)

This fixes #49384. Currently when we select a random subset of seed
nodes from a list, it is possible for 0 seeds to be selected. This test
depends on at least 1 seed being selected.

Add the simple strategy to cluster settings (#49414)

This is related to #49067. This commit adds the simple connection
strategy settings and strategy mode setting to the cluster settings
registry. With these changes, the simple connection mode can be used.
Additionally, it adds validation to ensure that settings cannot be
misconfigured.

[7.x][ML] Explain data frame analytics API (#49455) (#49504)
This commit replaces the _estimate_memory_usage API with
a new API, the _explain API.

The API consolidates information that is useful before
creating a data frame analytics job.

It includes:

- memory estimation
- field selection explanation

Memory estimation is moved here from what was previously
calculated in the _estimate_memory_usage API.

Field selection is a new feature that explains to the user
whether each available field was selected to be included or
not in the analysis. In the case it was not included, it also
explains the reason why.

This commit adds a deprecation warning when starting
a node where either of the server contexts
(xpack.security.transport.ssl and xpack.security.http.ssl)
meet either of these conditions:

1. The server lacks a certificate/key pair (i.e. neither
   ssl.keystore.path not ssl.certificate are configured)
2. The server has some ssl configuration, but ssl.enabled is not
   specified. This new validation does not care whether ssl.enabled is
   true or false (though other validation might), it simply makes it
   an error to configure server SSL without being explicit about
   whether to enable that configuration.

This separates out the `definition` object from being stored within the configuration object in the index. 

This allows us to gather the config object without decompressing a potentially large definition.

Additionally, `input` is moved to the TrainedModelConfig object and out of the definition. This is so the trained input fields are accessible outside the potentially large model definition.

Simplify usage of Gradle Shadow plugin (#48478) (#48597)
This commit simplifies and standardizes our usage of the Gradle Shadow
plugin to conform more to plugin conventions. The custom "bundle" plugin
has been removed as it's not necessary and performs the same function
as the Shadow plugin's default behavior with existing configurations.

Additionally, this removes unnecessary creation of a "nodeps" artifact,
which is unnecessary because by default project dependencies will in
fact use the non-shadowed JAR unless explicitly depending on the
"shadow" configuration.

Finally, we've cleaned up the logic used for unit testing, so we are
now correctly testing against the shadow JAR when the plugin is applied.
This better represents a real-world scenario for consumers and provides
better test coverage for incorrectly declared dependencies.

Make BytesReference an interface (#48486)
BytesReference is currently an abstract class which is extended by
various implementations. This makes it very difficult to use the
delegation pattern. The implication of this is that our releasable
BytesReference is a PagedBytesReference type and cannot be used as a
generic releasable bytes reference that delegates to any reference type.
This commit makes BytesReference an interface and introduces an
AbstractBytesReference for common functionality.

Michael Basnight c19379ef31 Remove random when using HLRC sync and async calls (#48211)
This commit removes the randomization used by every execute call in the
high level rest tests. Previously every execute call, which can be many
calls per single test, would rely on a random boolean to determine if
they should use the sync or async methods provided to the execute
method. This commit runs the tests twice, using two different clusters,
both of them providing the value one time via a sysprop. This ensures
that the whole suite of tests is run using the sync and async code
paths.

Fix security origin for TokenService#findActiveTokensFor... (#47418) (#48280)
All internal searches (triggered by APIs) across the .security index
must be performed while "under the security origin". Otherwise,
the search is performed in the context of the caller which most
likely does not have privileges to search .security (hopefully).
This commit fixes this in the case of two methods in the
TokenService and corrects an overly done such context switch
in the ApiKeyService.

In addition, this makes all tests from the client/rest-high-level
module execute as an all mighty administrator,
but not a literal superuser.

that allows document being ingested to be enriched with data from other indices.

Besides a new enrich processor, this PR adds several APIs to manage an enrich policy.
An enrich policy is in charge of making the data from other indices available to the enrich processor in an efficient manner.

[ML][7.x] Add lazy assignment job config option (#47993)
This change adds:

- A new option, allow_lazy_open, to anomaly detection jobs
- A new option, allow_lazy_start, to data frame analytics jobs

Both work in the same way: they allow a job to be
opened/started even if no ML node exists that can
accommodate the job immediately. In this situation
the job waits in the opening/starting state until ML
node capacity is available. (The starting state for data
frame analytics jobs is new in this change.)

Additionally, the ML nightly maintenance tasks now
creates audit warnings for ML jobs that are unassigned.
This means that jobs that cannot be assigned to an ML
node for a very long time will show a yellow warning
triangle in the UI.

A final change is that it is now possible to close a job
that is not assigned to a node without using force.
This is because previously jobs that were open but
not assigned to a node were an aberration, whereas
after this change they'll be relatively common.

Add Pause/Resume Auto Follower APIs (#47510) (#47904)
This commit adds two APIs that allow to pause and resume
CCR auto-follower patterns:

// pause auto-follower
POST /_ccr/auto_follow/my_pattern/pause

// resume auto-follower
POST /_ccr/auto_follow/my_pattern/resume

The ability to pause and resume auto-follow patterns can be
useful in some situations, including the rolling upgrades of
cluster using a bi-directional cross-cluster replication scheme
(see #46665).

This commit adds a new active flag to the AutoFollowPattern
and adapts the AutoCoordinator and AutoFollower classes so
that it stops to fetch remote's cluster state when all auto-follow
patterns associate to the remote cluster are paused.

When an auto-follower is paused, remote indices that match the
pattern are just ignored: they are not added to the pattern's
followed indices uids list that is maintained in the local cluster
state. This way, when the auto-follow pattern is resumed the
indices created in the remote cluster in the meantime will be
picked up again and added as new following indices. Indices
created and then deleted in the remote cluster will be ignored
as they won't be seen at all by the auto-follower pattern at
resume time.

Currently there are two issues with serializing BulkByScrollResponse.
First, when deserializing from XContent, indexing exceptions and search

from the exception. However, the exception class is not always correctly
retained when serialized.

failure.

Add 'create_doc' index privilege (#45806) (#47645)
Use case:
User with `create_doc` index privilege will be allowed to only index new documents
either via Index API or Bulk API.

There are two cases that we need to think:
- **User indexing a new document without specifying an Id.**
   For this ES auto generates an Id and now ES version 7.5.0 onwards defaults to `op_type` `create` we just need to authorize on the `op_type`.
- **User indexing a new document with an Id.**
   This is problematic as we do not know whether a document with Id exists or not.
   If the `op_type` is `create` then we can assume the user is trying to add a document, if it exists it is going to throw an error from the index engine.

Given these both cases, we can safely authorize based on the `op_type` value. If the value is `create` then the user with `create_doc` privilege is authorized to index new documents.

In the `AuthorizationService` when authorizing a bulk request, we check the implied action.
This code changes that to append the `:op_type/index` or `:op_type/create`
to indicate the implied index action.

Alpar Torok 0a14bb174f Remove eclipse conditionals (#44075)
* Remove eclipse conditionals

We used to have some meta projects with a `-test` prefix because
historically eclipse could not distinguish between test and main
source-sets and could only use a single classpath.
This is no longer the case for the past few Eclipse versions.

This PR adds the necessary configuration to correctly categorize source
folders and libraries.
With this change eclipse can import projects, and the visibility rules
are correct e.x. auto compete doesn't offer classes from test code or
`testCompile` dependencies when editing classes in `main`.

Unfortunately the cyclic dependency detection in Eclipse doesn't seem to
take the difference between test and non test source sets into account,
but since we are checking this in Gradle anyhow, it's safe to set to
`warning` in the settings. Unfortunately there is no setting to ignore
it.

This might cause problems when building since Eclipse will probably not
know the right order to build things in so more wirk might be necesarry.

* Add API to execute SLM retention on-demand (#47405)

This is a backport of #47405

This commit adds the `/_slm/_execute_retention` API endpoint. This

This in particular allows us to run retention without scheduling it
(for entirely manual invocation) or perform a one-off cleanup.

This commit also includes HLRC for the new API, and fixes an issue
in SLMSnapshotBlockingIntegTests where retention invoked prior to the
test completing could resurrect an index the internal test cluster
cleanup had already deleted.

Add config namespace in get policy api response (#47162)
Currently the policy config is placed directly in the json object
of the toplevel `policies` array field. For example:

```
{
    "policies": [
        {
            "match": {
                "name" : "my-policy",
                "indices" : ["users"],
                "match_field" : "email",
                "enrich_fields" : [
                    "first_name",
                    "last_name",
                    "city",
                    "zip",
                    "state"
                ]
            }
        }
    ]
}
```

This change adds a `config` field in each policy json object:

```
{
    "policies": [
        {
            "config": {
                "match": {
                    "name" : "my-policy",
                    "indices" : ["users"],
                    "match_field" : "email",
                    "enrich_fields" : [
                        "first_name",
                        "last_name",
                        "city",
                        "zip",
                        "state"
                    ]
                }
            }
        }
    ]
}
```

This allows us in the future to add other information about policies
in the get policy api response.

The UI will consume this API to build an overview of all policies.
The UI may in the future include additional information about a policy
and the plan is to include that in the get policy api, so that this
information can be gathered in a single api call.

An example of the information that is likely to be added is:
* Last policy execution time
* The status of a policy (executing, executed, unexecuted)
* Information about the last failure if exists

Convert most awaitBusy calls to assertBusy (#45794) (#47112)
Backport of #45794 to 7.x. Convert most `awaitBusy` calls to
`assertBusy`, and use asserts where possible. Follows on from #28548 by
@liketic.

There were a small number of places where it didn't make sense to me to
call `assertBusy`, so I kept the existing calls but renamed the method to
`waitUntil`. This was partly to better reflect its usage, and partly so
that anyone trying to add a new call to awaitBusy wouldn't be able to find
it.

I also didn't change the usage in `TransportStopRollupAction` as the
comments state that the local awaitBusy method is a temporary
copy-and-paste.

Other changes:

  * Rework `waitForDocs` to scale its timeout. Instead of calling
    `assertBusy` in a loop, work out a reasonable overall timeout and await
    just once.
  * Some tests failed after switching to `assertBusy` and had to be fixed.
  * Correct the expect templates in AbstractUpgradeTestCase.  The ES
    Security team confirmed that they don't use templates any more, so
    remove this from the expected templates. Also rewrite how the setup
    code checks for templates, in order to give more information.
  * Remove an expected ML template from XPackRestTestConstants The ML team
    advised that the ML tests shouldn't be waiting for any
    `.ml-notifications*` templates, since such checks should happen in the
    production code instead.
  * Also rework the template checking code in `XPackRestTestHelper` to give
    more helpful failure messages.
  * Fix issue in `DataFrameSurvivesUpgradeIT` when upgrading from < 7.4

[Backport] Validate `query` field when creating roles (#46275) (#47094)
In the current implementation, the validation of the role query
occurs at runtime when the query is being executed.

This commit adds validation for the role query when creating a role
but not for the template query as we do not have the runtime
information required for evaluating the template query (eg. authenticated user's
information). This is similar to the scripts that we
store but do not evaluate or parse if they are valid queries or not.

For validation, the query is evaluated (if not a template), parsed to build the
QueryBuilder and verify if the query type is allowed.

Add support for POST requests to SLM Execute API (#47061)
This commit adds support for POST requests to the SLM `_execute` API,
because POST is a more appropriate HTTP verb for this action as it is
not idempotent. The docs are also changed to favor POST over PUT,
although PUT is not removed or officially deprecated.

* [ML][Inference] Feature pre-processing objects and functions (#46777)

To support inference on pre-trained machine learning models, some basic feature encoding will be necessary. I am using a named object serialization approach so new encodings/pre-processing steps could be added in the future. 

This PR lays down the ground work for 3 basic encodings:

* HotOne
* Target Mean
* Frequency

More feature encodings or pre-processings could be added in the future:

* Handling missing columns
* Standardization
* Label encoding
* etc....

Add submitDeleteByQueryTask method to RestHighLevelClient (#46833)
The HLRC has a method for reindex, that allows to trigger an async reindex by running RestHighLevelClient.submitReindexTask and RestHighLevelClient.reindex. The delete by query however only has an RestHighLevelClient.deleteByQuery method (and its async counterpart), but no RestHighLevelClient.submitDeleteByQueryTask. So add RestHighLevelClient.submitDeleteByQueryTask

Change HLRC count request to accept a QueryBuilder (#46904)
Currently the CountRequest accepts a search source builder, while the
RestCountAction only accepts a top level query object. This can lead
to confusion if another element (e.g. aggregations) is specified,
because that will be ignored on the server side in RestCountAction.

By deprecating the current setter & constructor that accept a
SearchSourceBuilder and adding replacement that accepts a QueryBuilder
it is clear what the count api can handle from HLRC side.

Fix flaky test addSnapshotLifecyclePolicy (#46881) (#46912)
* addSnapshotLifecyclePolicy drop version assertion

This drops the assertion on the policy version (which was pinned to 1L)
as we want to execute both put policy apis (sync and async) for
documentation purposes. This will sometimes (depending on the async
call) yield a version of 2L. Waiting for the async call to always
complete could be an option but the test is already rather slow and it's
a bit of an overkill as we're already verifying the policy was created.

Luca Cavanna cfb186afaf Add support for cancelling async requests in low-level REST client (#45379)
The low-level REST client exposes a `performRequestAsync` method that
allows to send async requests, but today it does not expose the ability
to cancel such requests. That is something that the underlying apache
async http client supports, and it makes sense for us to expose.

This commit adds a return value to the `performRequestAsync` method,
which is backwards compatible. A `Cancellable` object gets returned,
which exposes a `cancel` public method. When calling `cancel`, the
on-going request associated with the returned `Cancellable` instance
will be cancelled by calling its `abort` method. This works throughout
multiple retries, though some special care was needed for the case where
`cancel` is called between different attempts (when one attempt has
failed and the consecutive one has not been sent yet).

Note that cancelling a request on the client side does not automatically 
translate to cancelling the server side execution of it. That needs to be 
specifically implemented, which is on the work for the search API (see #43332).

Add retention to Snapshot Lifecycle Management (backport of #4… (#46506)
* Add retention to Snapshot Lifecycle Management (#46407)

This commit adds retention to the existing Snapshot Lifecycle Management feature (#38461) as described in #43663. This allows a user to configure SLM to automatically delete older snapshots based on a number of criteria.

An example policy would look like:

```
PUT /_slm/policy/snapshot-every-day
{
  "schedule": "0 30 2 * * ?",
  "name": "<production-snap-{now/d}>",
  "repository": "my-s3-repository",
  "config": {
    "indices": ["foo-*", "important"]
  },
  // Newly configured retention options
  "retention": {
    // Snapshots should be deleted after 14 days
    "expire_after": "14d",
    // Keep a maximum of thirty snapshots
    "max_count": 30,
    // Keep a minimum of the four most recent snapshots
    "min_count": 4
  }
}
```

SLM Retention is run on a scheduled configurable with the `slm.retention_schedule` setting, which supports cron expressions. Deletions are run for a configurable time bounded by the `slm.retention_duration` setting, which defaults to 1 hour.

Included in this work is a new SLM stats API endpoint available through

``` json
GET /_slm/stats
```

That returns statistics about snapshot taken and deleted, as well as successful retention runs, failures, and the time spent deleting snapshots. #45362 has more information as well as an example of the output. These stats are also included when retrieving SLM policies via the API.

* Time-bound deletion of snapshots in retention delete function (#45065)

* Time-bound deletion of snapshots in retention delete function

With a cluster that has a large number of snapshots, it's possible that
snapshot deletion can take a very long time (especially since deletes
currently have to happen in a serial fashion). To prevent snapshot
deletion from taking forever in a cluster and blocking other operations,
this commit adds a setting to allow configuring a maximum time to spend
deletion snapshots during retention. This dynamic setting defaults to 1
hour and is best-effort, meaning that it doesn't hard stop a deletion
at an hour mark, but ensures that once the time has passed, all
subsequent deletions are deferred until the next retention cycle.

* Add SLM metrics gathering and endpoint

This commit adds the infrastructure to gather metrics about the different SLM actions that a cluster
takes. These actions are stored in `SnapshotLifecycleStats` and perpetuated in cluster state. The
stats stored include the number of snapshots taken, failed, deleted, the number of retention runs,
as well as per-policy counts for snapshots taken, failed, and deleted. It also includes the amount
of time spent deleting snapshots from SLM retention.

This commit also adds an endpoint for retrieving all stats (further commits will expose this in the
SLM get-policy API) that looks like:

```
GET /_slm/stats
{
  "retention_runs" : 13,
  "retention_failed" : 0,
  "retention_timed_out" : 0,
  "retention_deletion_time" : "1.4s",
  "retention_deletion_time_millis" : 1404,
  "policy_metrics" : {
    "daily-snapshots2" : {
      "snapshots_taken" : 7,
      "snapshots_failed" : 0,
      "snapshots_deleted" : 6,
      "snapshot_deletion_failures" : 0
    },
    "daily-snapshots" : {
      "snapshots_taken" : 12,
      "snapshots_failed" : 0,
      "snapshots_deleted" : 12,

  "total_snapshots_taken" : 19,
  "total_snapshots_failed" : 0,
  "total_snapshots_deleted" : 18,
  "total_snapshot_deletion_failures" : 6
}
```

This does not yet include HLRC for this, as this commit is quite large on its own. That will be
added in a subsequent commit.

- a repo cleanup in progress
- a restore currently running

Add `manage_own_api_key` cluster privilege (#45897) (#46023)
The existing privilege model for API keys with privileges like
`manage_api_key`, `manage_security` etc. are too permissive and
we would want finer-grained control over the cluster privileges
for API keys. Previously APIs created would also need these
privileges to get its own information.

This commit adds support for `manage_own_api_key` cluster privilege
which only allows api key cluster actions on API keys owned by the
currently authenticated user. Also adds support for retrieval of
the API key self-information when authenticating via API key
without the need for the additional API key privileges.
To support this privilege, we are introducing additional
authentication context along with the request context such that
it can be used to authorize cluster actions based on the current
user authentication.

The API key get and invalidate APIs introduce an `owner` flag
that can be set to true if the API key request (Get or Invalidate)
is for the API keys owned by the currently authenticated user only.
In that case, `realm` and `username` cannot be set as they are
assumed to be the currently authenticated ones.

The changes cover HLRC changes, documentation for the API changes.

PKI realm authentication delegation (#45906)
This commit introduces PKI realm delegation. This feature
supports the PKI authentication feature in Kibana.

In essence, this creates a new API endpoint which Kibana must
call to authenticate clients that use certificates in their TLS
connection to Kibana. The API call passes to Elasticsearch the client's
certificate chain. The response contains an access token to be further
used to authenticate as the client. The client's certificates are validated
by the PKI realms that have been explicitly configured to permit
certificates from the proxy (Kibana). The user calling the delegation
API must have the delegate_pki privilege.

[7.x][ML] Improve progress reportings for DF analytics (#45856) (#45910)
Previously, the stats API reports a progress percentage
for DF analytics tasks that are running and are in the
`reindexing` or `analyzing` state.

This means that when the task is `stopped` there is no progress
reported. Thus, one cannot distinguish between a task that never
run to one that completed.

In addition, there are blind spots in the progress reporting.
In particular, we do not account for when data is loaded into the
process. We also do not account for when results are written.

This commit addresses the above issues. It changes progress
to being a list of objects, each one describing the phase
and its progress as a percentage. We currently have 4 phases:
reindexing, loading_data, analyzing, writing_results.

When the task stops, progress is persisted as a document in the
state index. The stats API now reports progress from in-memory
if the task is running, or returns the persisted document
(if there is one).

Change how type is stored in an enrich policy. (#45789)
A policy type controls how the enrich index is created and
the query executed against the match field. Currently there
is a single policy type (`exact_match`). In the near future
more policy types will be added and different policy may have
different configuration options.

For this reason type should be a json object instead of a string field:

```
{
   "exact_match": {
      ...
   }
}
```

instead of:

```
{
  "type": "exact_match",
  ...
}
```

This will make streaming parsing of enrich policies easier as in the
new format, the parsing code can know ahead what configuration fields
to expect. In the latter format that is not possible if the type field
appears not as the first field.

Repository Cleanup Endpoint (#43900) (#45780)
* Repository Cleanup Endpoint (#43900)

* Snapshot cleanup functionality via transport/REST endpoint.
* Added all the infrastructure for this with the HLRC and node client
* Made use of it in tests and resolved relevant TODO
* Added new `Custom` CS element that tracks the cleanup logic.
Kept it similar to the delete and in progress classes and gave it
some (for now) redundant way of handling multiple cleanups but only allow one
* Use the exact same mechanism used by deletes to have the combination
of CS entry and increment in repository state ID provide some
concurrency safety (the initial approach of just an entry in the CS
was not enough, we must increment the repository state ID to be safe
against concurrent modifications, otherwise we run the risk of "cleaning up"
blobs that just got created without noticing)
* Isolated the logic to the transport action class as much as I could.
It's not ideal, but we don't need to keep any state and do the same
for other repository operations
(like getting the detailed snapshot shard status)

Michael Basnight e3373d349b Consolidate enrich list all and get by name APIs (#45705)
The get and list APIs are a single API in this commit. Whether
requesting one named policy or all policies, a list of policies is
returened. The list API code has all been removed and the GET api is
what remains, which contains much of the list response code.

Clean SLM and ongoing snapshots in test framework (#45564)
Adjusts the cluster cleanup routine in ESRestTestCase to clean up SLM
test cases, and optionally wait for all snapshots to be deleted.

Waiting for all snapshots to be deleted, rather than failing if any are
in progress, is necessary for tests which use SLM policies because SLM
policies may be in the process of executing when the test ends.

Jim Ferenczi 79a1390935 Add mapper-extras and the RankFeatureQuery in the hlrc (#43713)
This change adds the support for the RankFeatureQuery in the HLRC by
providing an extra dependency on mapper-extras-client. It also removes
the dependency on lang-painless in mapper-extras which is not needed
anymore since the move of the vector field into a dedicated module.

returning a policy that looks like:

```json

    "version" : 1,
    "modified_date" : "2019-08-05T18:41:48.778Z",

        ],

      },

      }
    },
    "last_success" : {

      "time_string" : "2019-08-05T18:42:23.257Z",
      "time" : 1565030543257
    },
    "next_execution" : "2019-08-06T01:30:00.000Z",
    "next_execution_millis" : 1565055000000,
    "in_progress" : {
      "name" : "production-snap-2019.08.05-oxctmnobqye3luim4uejhg",

      "state" : "STARTED",
      "start_time" : "2019-08-05T18:42:22.998Z",
      "start_time_millis" : 1565030542998
    }
  }
}
```

These are only visible while the snapshot is being taken (or failed),
since it reads from the cluster state rather than from the repository
itself.

Use index for peer recovery instead of translog (#45137)
Today we recover a replica by copying operations from the primary's translog.
However we also retain some historical operations in the index itself, as long
as soft-deletes are enabled. This commit adjusts peer recovery to use the
operations in the index for recovery rather than those in the translog, and
ensures that the replication group retains enough history for use in peer
recovery by means of retention leases.

Yannick Welsch 0ce841915c Add Clone Index API (#44267)
Adds an API to clone an index. This is similar to the index split and shrink APIs, just with the
difference that the number of primary shards is kept the same. In case where the filesystem
provides hard-linking capabilities, this is a very cheap operation.

Indexing cloning can be done by running `POST my_source_index/_clone/my_target_index` and it
supports the same options as the split and shrink APIs.

[ML-DataFrame] Remove ID field from data frame indexer stats (#44848)
This is a followup to #44350. The indexer stats used to
be persisted standalone, but now are only persisted as
part of a state-and-stats document. During the review
of #44350 it was decided that we'll stick with this
design, so there will never be a need for an indexer
stats object to store its transform ID as it is stored
on the enclosing document. This PR removes the indexer
stats document ID.

Ioannis Kakavas 3714cb63da Allow parsing the value of java.version sysprop (#44017)
We often start testing with early access versions of new Java
versions and this have caused minor issues in our tests
(i.e. #43141) because the version string that the JVM reports
cannot be parsed as it ends with the string -ea.

This commit changes how we parse and compare Java versions to
allow correct parsing and comparison of the output of java.version
system property that might include an additional alphanumeric
part after the version numbers
 (see [JEP 223[(https://openjdk.java.net/jeps/223)). In short it 
handles a version number part, like before, but additionally a 
PRE part that matches ([a-zA-Z0-9]+).

It also changes a number of tests that would attempt to parse
java.specification.version in order to get the full version
of Java. java.specification.version only contains the major
version and is thus inappropriate when trying to compare against
a version that might contain a minor, patch or an early access
part. We know parse java.version that can be consistently
parsed.

[7.x] Add Snapshot Lifecycle Management (#44382)
* Add Snapshot Lifecycle Management (#43934)

* Add SnapshotLifecycleService and related CRUD APIs

This commit adds `SnapshotLifecycleService` as a new service under the ilm
plugin. This service handles snapshot lifecycle policies by scheduling based on
the policies defined schedule.

This also includes the get, put, and delete APIs for these policies

Relates to #38461

* Make scheduledJobIds return an immutable set

* Use Object.equals for SnapshotLifecyclePolicy

* Remove unneeded TODO

* Implement ToXContentFragment on SnapshotLifecyclePolicyItem

* Copy contents of the scheduledJobIds

* Handle snapshot lifecycle policy updates and deletions (#40062)

(Note this is a PR against the `snapshot-lifecycle-management` feature branch)

This adds logic to `SnapshotLifecycleService` to handle updates and deletes for
snapshot policies. Policies with incremented versions have the old policy
cancelled and the new one scheduled. Deleted policies have their schedules
cancelled when they are no longer present in the cluster state metadata.

Relates to #38461

* Take a snapshot for the policy when the SLM policy is triggered (#40383)

(This is a PR for the `snapshot-lifecycle-management` branch)

This commit fills in `SnapshotLifecycleTask` to actually perform the
snapshotting when the policy is triggered. Currently there is no handling of the
results (other than logging) as that will be added in subsequent work.

This also adds unit tests and an integration test that schedules a policy and
ensures that a snapshot is correctly taken.

Relates to #38461

* Record most recent snapshot policy success/failure (#40619)

Keeping a record of the results of the successes and failures will aid
troubleshooting of policies and make users more confident that their
snapshots are being taken as expected.

This is the first step toward writing history in a more permanent
fashion.

* Validate snapshot lifecycle policies (#40654)

(This is a PR against the `snapshot-lifecycle-management` branch)

With the commit, we now validate the content of snapshot lifecycle policies when
the policy is being created or updated. This checks for the validity of the id,
name, schedule, and repository. Additionally, cluster state is checked to ensure
that the repository exists prior to the lifecycle being added to the cluster
state.

Part of #38461

* Hook SLM into ILM's start and stop APIs (#40871)

(This pull request is for the `snapshot-lifecycle-management` branch)

This change allows the existing `/_ilm/stop` and `/_ilm/start` APIs to also
manage snapshot lifecycle scheduling. When ILM is stopped all scheduled jobs are
cancelled.

Relates to #38461

* Add tests for SnapshotLifecyclePolicyItem (#40912)

Adds serialization tests for SnapshotLifecyclePolicyItem.

* Fix improper import in build.gradle after master merge

* Add human readable version of modified date for snapshot lifecycle policy (#41035)

* Add human readable version of modified date for snapshot lifecycle policy

This small change changes it from:

```
...
"modified_date": 1554843903242,
...
```

To

```
...
"modified_date" : "2019-04-09T21:05:03.242Z",
"modified_date_millis" : 1554843903242,
...
```

Including the `"modified_date"` field when the `?human` field is used.

Relates to #38461

* Fix test

* Add API to execute SLM policy on demand (#41038)

This commit adds the ability to perform a snapshot on demand for a policy. This
can be useful to take a snapshot immediately prior to performing some sort of
maintenance.

```json
PUT /_ilm/snapshot/<policy>/_execute
```

And it returns the response with the generated snapshot name:

```json
{
  "snapshot_name" : "production-snap-2019.04.09-rfyv3j9qreixkdbnfuw0ug"
}
```

Note that this does not allow waiting for the snapshot, and the snapshot could
still fail. It *does* record this information into the cluster state similar to
a regularly trigged SLM job.

Relates to #38461

* Add next_execution to SLM policy metadata (#41221)

* Add next_execution to SLM policy metadata

This adds the next time a snapshot lifecycle policy will be executed when
retriving a policy's metadata, for example:

{
  "production" : {
    "version" : 1,
    "modified_date" : "2019-04-15T21:16:21.865Z",
    "modified_date_millis" : 1555362981865,
    "policy" : {
      "name" : "<production-snap-{now/d}>",
      "schedule" : "*/30 * * * * ?",
      "repository" : "repo",

          "foo-*",
          "important"

* Fix and enhance tests

* Figured out how to Cron

* Change SLM endpoint from /_ilm/* to /_slm/* (#41320)

This commit changes the endpoint for snapshot lifecycle management from:

```
GET /_ilm/snapshot/<policy>
```

to:

```
GET /_slm/policy/<policy>
```

It mimics the ILM path only using `slm` instead of `ilm`.

* Add initial documentation for SLM (#41510)

* Add initial documentation for SLM

This adds the initial documentation for snapshot lifecycle management.

It also includes the REST spec API json files since they're sort of
documentation.

Relates to #38461

* Add `manage_slm` and `read_slm` roles (#41607)

* Add `manage_slm` and `read_slm` roles

This adds two more built in roles -

`manage_slm` which has permission to perform any of the SLM actions, as well as
stopping, starting, and retrieving the operation status of ILM.

`read_slm` which has permission to retrieve snapshot lifecycle policies as well
as retrieving the operation status of ILM.

Relates to #38461

* Add execute to the test

* Fix ilm -> slm typo in test

* Record SLM history into an index (#41707)

It is useful to have a record of the actions that Snapshot Lifecycle
Management takes, especially for the purposes of alerting when a
snapshot fails or has not been taken successfully for a certain amount of
time.

This adds the infrastructure to record SLM actions into an index that
can be queried at leisure, along with a lifecycle policy so that this
history does not grow without bound.

Additionally,
SLM automatically setting up an index + lifecycle policy leads to
`index_lifecycle` custom metadata in the cluster state, which some of
the ML tests don't know how to deal with due to setting up custom
`NamedXContentRegistry`s.  Watcher would cause the same problem, but it
is already disabled (for the same reason).

* High Level Rest Client support for SLM (#41767)

* High Level Rest Client support for SLM

This commit add HLRC support for SLM.

Relates to #38461

* Fill out documentation tests with tags

* Add more callouts and asciidoc for HLRC

* Update javadoc links to real locations

* Add security test testing SLM cluster privileges (#42678)

* Add security test testing SLM cluster privileges

This adds a test to `PermissionsIT` that uses the `manage_slm` and `read_slm`
cluster privileges.

Relates to #38461

* Don't redefine vars

*  Add Getting Started Guide for SLM  (#42878)

This commit adds a basic Getting Started Guide for SLM.

* Include SLM policy name in Snapshot metadata (#43132)

Keep track of which SLM policy in the metadata field of the Snapshots
taken by SLM. This allows users to more easily understand where the
snapshot came from, and will enable future SLM features such as
retention policies.

* Fix compilation after master merge

* [TEST] Move exception wrapping for devious exception throwing

Fixes an issue where an exception was created from one line and thrown in another.

* Fix SLM for the change to AcknowledgedResponse

* Add Snapshot Lifecycle Management Package Docs (#43535)

* Fix compilation for transport actions now that task is required

* Add a note mentioning the privileges needed for SLM (#43708)

This adds a note to the top of the "getting started with SLM"
documentation mentioning that there are two built-in privileges to
assist with creating roles for SLM users and administrators.
