Validate role templates before saving role mapping (#52636) (#54059)
Role names are now compiled from role templates before role mapping is saved.
This serves as validation for role templates to prevent malformed and invalid scripts
to be persisted, which could later break authentication.

[7.x][ML] Data frame analytics data counts (#53998) (#54031)
This commit instruments data frame analytics
with stats for the data that are being analyzed.
In particular, we count training docs, test docs,
and skipped docs.

In order to account docs with missing values as skipped
docs for analyses that do not support missing values,
this commit changes the extractor so that it only ignores
docs with missing values when it collects the data summary,
which is used to estimate memory usage.

[ML] adds multi-class feature importance support (#53803) (#54024)
Adds multi-class feature importance calculation. 

Feature importance objects are now mapped as follows
(logistic) Regression:
```
{
   "feature_name": "feature_0",
   "importance": -1.3
}
```
Multi-class [class names are `foo`, `bar`, `baz`]
```
{ 
   “feature_name”: “feature_0”, 
   “importance”: 2.0, // sum(abs()) of class importances
   “foo”: 1.0, 
   “bar”: 0.5, 
   “baz”: -0.5 
},
```

For users to get the full benefit of aggregating and searching for feature importance, they should update their index mapping as follows (before turning this option on in their pipelines)
```
 "ml.inference.feature_importance": {
          "type": "nested",
          "dynamic": true,
          "properties": {
            "feature_name": {
              "type": "keyword"
            },
            "importance": {
              "type": "double"
            }
          }
        }
```
The mapping field name is as follows
`ml.<inference.target_field>.<inference.tag>.feature_importance`
if `inference.tag` is not provided in the processor definition, it is not part of the field path.
`inference.target_field` is defaulted to `ml.inference`.
//cc @lcawl ^ Where should we document this?

If this makes it in for 7.7, there shouldn't be any feature_importance at inference BWC worries as 7.7 is the first version to have it.

Refactor global build info plugin to leverage JavaInstallationRegistry (#54026)
This commit removes the configuration time vs execution time distinction
with regards to certain BuildParms properties. Because of the cost of
determining Java versions for configuration JDK locations we deferred
this until execution time. This had two main downsides. First, we had
to implement all this build logic in tasks, which required a bunch of
additional plumbing and complexity. Second, because some information
wasn't known during configuration time, we had to nest any build logic
that depended on this in awkward callbacks.

We now defer to the JavaInstallationRegistry recently added in Gradle.
This utility uses a much more efficient method for probing Java
installations vs our jrunscript implementation. This, combined with some
optimizations to avoid probing the current JVM as well as deferring
some evaluation via Providers when probing installations for BWC builds
we can maintain effectively the same configuration time performance
while removing a bunch of complexity and runtime cost (snapshotting
inputs for the GenerateGlobalBuildInfoTask was very expensive). The end
result should be a much more responsive build execution in almost all
scenarios.

Move pipeline agg validation to coordinating node (backport of #53669) (#54019)
This moves the pipeline aggregation validation from the data node to the
coordinating node so that we, eventually, can stop sending pipeline
aggregations to the data nodes entirely. In fact, it moves it into the
"request validation" stage so multiple errors can be accumulated and
sent back to the requester for the entire request. We can't always take
advantage of that, but it'll be nice for folks not to have to play
whack-a-mole with validation.

This is implemented by replacing `PipelineAggretionBuilder#validate`
with:
```
protected abstract void validate(ValidationContext context);
```

The `ValidationContext` handles the accumulation of validation failures,
provides access to the aggregation's siblings, and implements a few
validation utility methods.

Reduce performance impact of ExitableDirectoryReader (#53978) (#54014)
Benchmarking showed that the effect of the ExitableDirectoryReader

[ML] adjusting feature importance mapping for multi-class support (#53821) (#54013)
Feature importance storage format is changing to encompass multi-class.

Feature importance objects are now mapped as follows
(logistic) Regression:
```
{
   "feature_name": "feature_0",
   "importance": -1.3
}
```
Multi-class [class names are `foo`, `bar`, `baz`]
```
{
   “feature_name”: “feature_0”,
   “importance”: 2.0, // sum(abs()) of class importances
   “foo”: 1.0,
   “bar”: 0.5,
   “baz”: -0.5
},
```

This change adjusts the mapping creation for analytics so that the field is mapped as a `nested` type.

Backport of async search changes (#53976)
* Get Async Search: omit _clusters section when empty (#53907)

The _clusters section is omitted by the search API whenever no remote clusters are searched. Async search should do the same, but Get Async Search returns a deserialized response, hence a weird `_clusters` section with all values set to `0` gets returned instead. In fact the recreated Clusters object is not the same object as the EMPTY constant, yet it has the same content.

This commit addresses this by changing the comparison in the `toXContent` method to not print out the section if the number of total clusters is `0`.

* Async search: remove version from response (#53960)

The goal of the version field was to quickly show when you can expect to find something new in the search response, compared to when nothing has changed. This can also be done by looking at the `_shards` section and `num_reduce_phases` returned with the search response. In fact when there has been one or more additional reduction of the results, you can expect new results in the search response. Otherwise, the `_shards` section could notify of additional failures of shards that have completed the query, but that is not a guarantee that their results will be exposed (only when the following partial reduction is performed their results will be available).

That said this commit clarifies this in the docs and removes the version field from the async search response

* Async Search: replicas to auto expand from 0 to 1 (#53964)

This way single node clusters that are green don't go yellow once async search is used, while
all the others still have one replica.

* [DOCS] address timing issue in async search docs tests (#53910)

The docs snippets for submit async search have proven difficult to test as it is not possible to guarantee that you get a response that is not final, even when providing `wait_for_completion=0`. In the docs we want to show though a proper long-running query, and its first response should be partial rather than final.

With this commit we adapt the docs snippets to show a partial response, and replace under the hood all that's needed to make the snippets tests succeed when we get a final response. Also, increased the timeout so we always get a final response.

[7.x][ML] Refactor DFA custom processor to cross validation splitter (#53915) (#53956)
While `CustomProcessor` is generic and allows for flexibility, there
are new requirements that make cross validation a concept it's hard
to abstract behind custom processor. In particular, we would like to
add data_counts to the DFA jobs stats. Counting training VS. test
docs would be a useful statistic. We would also want to add a
different cross validation strategy for multiclass classification.

This commit renames custom processors to cross validation splitters
which allows for those enhancements without cryptically doing
things as a side effect of the abstract custom processing.

Backport: initial data stream commit (#53959)
This commits adds a data stream feature flag, initial definition of a data stream and
the stubs for the data stream create, delete and get APIs. Also simple serialization
tests are added and a rest test to thest the data stream API stubs.

This is a large amount of code and mainly mechanical, but this commit should be
straightforward to review, because there isn't any real logic.

The data stream transport and rest action are behind the data stream feature flag and
are only intialized if the feature flag is enabled. The feature flag is enabled if
elasticsearch is build as snapshot or a release build and the
'es.datastreams_feature_flag_registered' is enabled.

The integ-test-zip sets the feature flag if building a release build, otherwise
rest tests would fail.

Yannick Welsch 060c72c799 Only link fd* files during source-only snapshot (#53463)
Source-only snapshots currently create a second full source-only copy of the shard on disk to
support incrementality during upload. Given that stored fields are occupying a substantial part
of a shard's storage, this means that clusters with source-only snapshots can require up to
50% more local storage. Ideally we would only generate source-only parts of the shard for the
things that need to be uploaded (i.e. do incrementality checks on original file instead of
trimmed-down source-only versions), but that requires much bigger changes to the snapshot
infrastructure. This here is an attempt to dramatically cut down on the storage used by the
source-only copy of the shard by soft-linking the stored-fields files (fd*) instead of copying
them.

Create API Key on behalf of other user (#53943)
This change adds a "grant API key action"

   POST /_security/api_key/grant

that creates a new API key using the privileges of one user ("the
system user") to execute the action, but creates the API key with
the roles of the second user ("the end user").

This allows a system (such as Kibana) to create API keys representing
the identity and access of an authenticated user without requiring
that user to have permission to create API keys on their own.

This also creates a new QA project for security on trial licenses and runs
the API key tests there

behavior, and NATIVE is not needed because it would always return true
since we should always have a basic license.

Alan Woodward d23112f441 Report parser name and location in XContent deprecation warnings (#53805)
It's simple to deprecate a field used in an ObjectParser just by adding deprecation
markers to the relevant ParseField objects. The warnings themselves don't currently
have any context - they simply say that a deprecated field has been used, but not
where in the input xcontent it appears. This commit adds the parent object parser
name and XContentLocation to these deprecation messages.

Note that the context is automatically stripped from warning messages when they
are asserted on by integration tests and REST tests, because randomization of
xcontent type during these tests means that the XContentLocation is not constant

Scripting: Per-context script cache, default off (#52855) (#53756)
* Adds per context settings:
  `script.context.${CONTEXT}.cache_max_size` ~
  `script.cache.max_size`

  `script.context.${CONTEXT}.cache_expire` ~
  `script.cache.expire`

  `script.context.${CONTEXT}.max_compilations_rate` ~
  `script.max_compilations_rate`

* Context cache is used if:
  `script.max_compilations_rate=use-context`.  This
  value is dynamically updatable, so users can
  switch back to the general cache if desired.

* Settings for context caches take the first value
  that applies:
  1) Context specific settings if set, eg
     `script.context.ingest.cache_max_size`
  2) Correlated general setting is set to the non-default
     value, eg `script.cache.max_size`
  3) Context default

The reason for 2's inclusion is to allow an easy
transition for users who've customized their general
cache settings.

Using the general cache settings for the context caches
results in higher effective settings, since they are
multiplied across the number of contexts.  So a general
cache max size of 200 will become 200 * # of contexts.
However, this behavior it will avoid users snapping to a
value that is too low for them.

Sometimes we want to deprecate and remove a ParseField entirely, without replacement;
for example, the various places where we specify a _type field in 7x. Currently we can
tell users only that a particular field name should not be used, and that another name should
be used in its place. This commit adds the ability to say that a field should not be used at
all.

Christoph Büscher 2c32173fce Fix ReloadSynonymAnalyzerIT failure (#53663)
There is an assertion in ReloadAnalyzersResponse.merge that compares index names
of merged responses that was falsely using object equality instead of
String.equals(). In the past this didn't seem to matter but with changes in the
test setup we started to see failures. Correcting this and also simplifying test
a bit to be able to run it repeatedly if needed.

Avoid NPE in set_security_user without security (#53543)

Attempting to define a pipeline that used that processor would fail

Cumulative backport of async search changes (#53635)
* Submit async search to work only with POST (#53368)

Currently the submit async search API can be called using both GET and POST at REST, but given that it submits a call and creates internal state, POST should be the only allowed method.

* Refine SearchProgressListener internal API (#53373)

The following cumulative improvements have been made:
- rename `onReduce` and `notifyReduce` to `onFinalReduce` and `notifyFinalReduce`
- add unit test for `SearchShard`
- on* methods in `SearchProgressListener` shouldn't need to be public as they should never be called directly, they only need to be overridden hence they can be made protected. They are actually called directly from a test which required some adapting, like making `AsyncSearchTask.Listener` class package private instead of private
- Instead of overriding `getProgressListener` in `AsyncSearchTask`, as it feels weird to override a getter method, added a specific method that allows to retrieve the Listener directly without needing to cast it. Made the getter and setter for the listener final in the base class.
- rename `SearchProgressListener#searchShards` methods to `buildSearchShards` and make it static given that it accesses no instance members
- make `SearchShard` and `SearchShardTask` classes final

* Move async search yaml tests to x-pack yaml test folder (#53537)

The yaml tests for async search currently sit in its qa folder. There is no reason though for them to live in a separate folder as they don't require particular setup. This commit moves them to the main folder together with the other x-pack yaml tests so that they will be run by the client test runners too.

* [DOCS] Add temporary redirect for async-search (#53454)

The following API spec files contain a link to a not-yet-created
async search docs page:

* [async_search.delete.json][0]
* [async_search.get.json][1]
* [async_search.submit.json][2]

The Elaticsearch-js client uses these spec files to create their docs.
This created a broken link in the Elaticsearch-js docs, which has broken
the docs build.

This PR adds a temporary redirect for the docs page. This redirect
should be removed when the actual API docs are added.

Stop using round-tripped PipelineAggregators (backport of #53423) (#53629)
This begins to clean up how `PipelineAggregator`s and executed.
Previously, we would create the `PipelineAggregator`s on the data nodes
and embed them in the aggregation tree. When it came time to execute the
pipeline aggregation we'd use the `PipelineAggregator`s that were on the
first shard's results. This is inefficient because:
1. The data node needs to make the `PipelineAggregator` only to
   serialize it and then throw it away.
2. The coordinating node needs to deserialize all of the
   `PipelineAggregator`s even though it only needs one of them.
3. You end up with many `PipelineAggregator` instances when you only
   really *need* one per pipeline.
4. `PipelineAggregator` needs to implement serialization.

This begins to undo these by building the `PipelineAggregator`s directly
on the coordinating node and using those instead of the
`PipelineAggregator`s in the aggregtion tree. In a follow up change
we'll stop serializing the `PipelineAggregator`s to node versions that
support this behavior. And, one day, we'll be able to remove
`PipelineAggregator` from the aggregation result tree entirely.

Importantly, this doesn't change how pipeline aggregations are declared
or parsed or requested. They are still part of the `AggregationBuilder`
tree because *that* makes sense.

Alexander Reelsen 7571ca437a Disable Watcher script optimization for stored scripts (#53497)
The watcher TextTemplateEngine uses a fast path mechanism where it
checks for the existence of `{{` to decide if a mustache script
required compilation. This does not work for stored script, as the field
that is checked contains the id of the script, which means, the name of
the script is returned as its value.

This commit checks for the script type and does not involve this fast
path check if a stored script is used.

Add new x-pack endpoints to track the progress of a search asynchronously (#49931) (#53591)
This change introduces a new API in x-pack basic that allows to track the progress of a search.
Users can submit an asynchronous search through a new endpoint called `_async_search` that
works exactly the same as the `_search` endpoint but instead of blocking and returning the final response when available, it returns a response after a provided `wait_for_completion` time.

````
GET my_index_pattern*/_async_search?wait_for_completion=100ms
{
  "aggs": {
    "date_histogram": {
      "field": "@timestamp",
      "fixed_interval": "1h"
    }
  }
}
````

If after 100ms the final response is not available, a `partial_response` is included in the body:

````
{
  "id": "9N3J1m4BgyzUDzqgC15b",
  "version": 1,
  "is_running": true,
  "is_partial": true,
  "response": {
   "_shards": {
       "total": 100,
       "successful": 5,
       "failed": 0
    },
    "total_hits": {
      "value": 1653433,
      "relation": "eq"
    },
    "aggs": {
      ...
    }
  }
}
````

The partial response contains the total number of requested shards, the number of shards that successfully returned and the number of shards that failed.
It also contains the total hits as well as partial aggregations computed from the successful shards.
To continue to monitor the progress of the search users can call the get `_async_search` API like the following:

````
GET _async_search/9N3J1m4BgyzUDzqgC15b/?wait_for_completion=100ms
````

That returns a new response that can contain the same partial response than the previous call if the search didn't progress, in such case the returned `version`
should be the same. If new partial results are available, the version is incremented and the `partial_response` contains the updated progress.
Finally if the response is fully available while or after waiting for completion, the `partial_response` is replaced by a `response` section that contains the usual _search response:

````
{
  "id": "9N3J1m4BgyzUDzqgC15b",
  "version": 10,
  "is_running": false,
  "response": {
     "is_partial": false,
     ...
  }
}
````

Asynchronous search are stored in a restricted index called `.async-search` if they survive (still running) after the initial submit. Each request has a keep alive that defaults to 5 days but this value can be changed/updated any time:
`````
GET my_index_pattern*/_async_search?wait_for_completion=100ms&keep_alive=10d
`````
The default can be changed when submitting the search, the example above raises the default value for the search to `10d`.
`````
GET _async_search/9N3J1m4BgyzUDzqgC15b/?wait_for_completion=100ms&keep_alive=10d
`````
The time to live for a specific search can be extended when getting the progress/result. In the example above we extend the keep alive to 10 more days.
A background service that runs only on the node that holds the first primary shard of the `async-search` index is responsible for deleting the expired results. It runs every hour but the expiration is also checked by running queries (if they take longer than the keep_alive) and when getting a result.

Like a normal `_search`, if the http channel that is used to submit a request is closed before getting a response, the search is automatically cancelled. Note that this behavior is only for the submit API, subsequent GET requests will not cancel if they are closed.

Asynchronous search are not persistent, if the coordinator node crashes or is restarted during the search, the asynchronous search will stop. To know if the search is still running or not the response contains a field called `is_running` that indicates if the task is up or not. It is the responsibility of the user to resume an asynchronous search that didn't reach a final response by re-submitting the query. However final responses and failures are persisted in a system index that allows
to retrieve a response even if the task finishes.

````
DELETE _async_search/9N3J1m4BgyzUDzqgC15b
````

The response is also not stored if the initial submit action returns a final response. This allows to not add any overhead to queries that completes within the initial `wait_for_completion`.

The `.async-search` index is a restricted index (should be migrated to a system index in +8.0) that is accessible only through the async search APIs. These APIs also ensure that only the user that submitted the initial query can retrieve or delete the running search. Note that admins/superusers would still be able to cancel the search task through the task manager like any other tasks.

[ML] Skeleton estimate_model_memory endpoint for anomaly detection (#53386)
This is a partial implementation of an endpoint for anomaly
detector model memory estimation.

It is not complete, lacking docs, HLRC and sensible numbers
for many anomaly detector configurations.  These will be
added in a followup PR in time for 7.7 feature freeze.

A skeleton endpoint is useful now because it allows work on
the UI side of the change to commence.  The skeleton endpoint
handles the same cases that the old UI code used to handle,
and produces very similar estimates for these cases.

Nhat Nguyen 24f114766f Fix doc_stats and segment_stats of ReadOnlyEngine (#53345)
We can't always have the same segment stats and doc stats between
InternalEngine and ReadOnlyEngine if there are some fully deleted
segments. ReadOnlyEngine always filters out them. InternalEngine,
however, will keep them if peer recovery retention leases exist or the
number of the retaining operations is non-zero.

This change reverts the fix in #51331 and uses the wrapped reader to
calculate the segment stats and doc stats. For the test, we need to
disable the extra retaining soft-deletes operations.

[ML] fixing data frame analysis test when two jobs are started in succession quickly (#53192) (#53332)
A previous change (#53029) is causing analysis jobs to wait for certain indices to be made available. While this it is good for jobs to wait, they could fail early on _start. 

This change will cause the persistent task to continually retry node assignment when the failure is due to shards not being available.

If the shards are not available by the time `timeout` is reached by the predicate, it is treated as a _start failure and the task is canceled. 

For tasks seeking a new assignment after a node failure, that behavior is unchanged.

SQL: transfer version compatibility decision to the server (#53082) (#53302)
This commit adds a new request object field, "version", containing the version of the requesting client. This parameter is now accepted - and for certain clients required - by the server and the request is validated against it. Currently server's and client's versions still need to be equal in order for the request to be accepted. Relaxing this check is going to be part of future work. 

On the clients' side, the only check remaining is to ensure that the peer server is supporting version backwards compatibility (i.e. is on, or newer than a certain release).

Implement hidden aliases (#52547)
This commit introduces hidden aliases. These are similar to hidden
indices, in that they are not visible by default, unless explicitly
specified by name or by indicating that hidden indices/aliases are
desired.

The new alias property, `is_hidden` is implemented similarly to
`is_write_index`, except that it must be consistent across all indices
with a given alias - that is, all indices with a given alias must
specify the alias as either hidden, or all specify it as non-hidden,
either explicitly or by omitting the `is_hidden` property.

[ML] Fix minor race condition in dataframe analytics _stop (#53029) (#53164)
Tests have been periodically failing due to a race condition on checking a recently `STOPPED` task's state. The `.ml-state` index is not created until the task has already been transitioned to `STARTED`. This allows the `_start` API call to return. But, if a user (or test) immediately attempts to `_stop` that job, the job could stop and the task removed BEFORE the `.ml-state|stats` indices are created/updated.

This change moves towards the task cleaning up itself in its main execution thread. `stop` flips the flag of the task to `isStopping` and now we check `isStopping` at every necessary method. Allowing the task to gracefully stop.

[ML] specifying missing_field_value value and using it instead of empty_string (#53108) (#53165)
For analytics, we need a consistent way of indicating when a value is missing. Inheriting from anomaly detection, analysis sent `""` when a field is missing. This works fine with numbers, but the underlying analytics process actually treats `""` as a category in categorical values. 

Consequently, you end up with this situation in the resulting model
```
{
              "frequency_encoding" : {
                "field" : "RainToday",
                "feature_name" : "RainToday_frequency",
                "frequency_map" : {
                  "" : 0.009844409027270245,
                  "No" : 0.6472019970785184,
                  "Yes" : 0.6472019970785184
                }
              }
            }
```
For inference this is a problem, because inference will treat missing values as `null`. And thus not include them on the infer call against the model.

This PR takes advantage of our new `missing_field_value` option and supplies `\0` as the value.

The assumption added in #52631 skips a problematic test
if it fails to create the required conditions for the
scenario it is supposed to be testing.  (This happens
very rarely.)

However, before skipping the test it needs to remove the
failed job it has created because the standard test
cleanup code treats failed jobs as fatal errors.

Introduce system index APIs for Kibana (#53035)
This commit introduces a module for Kibana that exposes REST APIs that
will be used by Kibana for access to its system indices. These APIs are wrapped
versions of the existing REST endpoints. A new setting is also introduced since
the Kibana system indices' names are allowed to be changed by a user in case
multiple instances of Kibana use the same instance of Elasticsearch.

Additionally, the ThreadContext has been extended to indicate that the use of
system indices may be allowed in a request. This will be built upon in the future
for the protection of system indices.
