Re-enable resolve index multi cluster test (#62365)
Backport of #62361 to 7.x branch.

This test was fine and shouldn't have been muted.
The test case class should have preserved data streams as part of #62205

Closes #62210

[7.x] Add "synthetics-*-*" templates for synthetics fleet data (#62193) (#62346)
* Add "synthetics-*-*" templates for synthetics fleet data

For the Elastic Agent we currently have `logs` and `metrics`, however, synthetic data doesn't belong
with those and thus we should have a place for it to live. This would be data reported from
heartbeat and under the 'monitoring' category.

This commit adds a composable index template for `synthetics-*-*` indices similar to the work in
 #56709 and #57629.

Resolves #61665

[ML] Add an assertion on annotations mappings to upgrade test (#62331)
The annotations index is not covered by the comparison between
mappings and templates, as it does not use an index template.

David Roberts e4275f3749 [ML] Use utility thread pool for memory estimation (#62314)
The job comms thread pool is intended for the long-running job
processes that do anomaly detection or data frame analytics and
count towards job count and memory limits.

This commit moves the short-lived memory estimation processes
to the ML utility thread pool.

Although this doesn't matter in most cases, at the limits of
scale it could mean that memory estimations would get in the way
of starting jobs, or would queue up for an excessive period of
time while waiting for jobs to finish.

[7.x] Add "content" tier as new "data_content" role (#62247) (#62322)
Similar to the work in #60994 where we introduced the `data_hot`, `data_warm`, etc node roles. This
introduces a new `data_content` node role to be used for the Content tier.

Currently this tier is not used anywhere, but subsequent work will use this tier.

[Enrich] add logging for when there are search/bulk failures on _execute (#62313) (#62320)
When calling `_execute` there is a chance that there will be bulk indexing failures 
or search failures. 

These will result in the call failing overall. But, no information is provided for troubleshooting the failure.

This commit adds logging to indicate the number of failures, and new debug level logging so that
failure details can be determined if necessary.

Nhat Nguyen 3d69b5c41e Introduce point in time APIs in x-pack basic (#61062)
This commit introduces a new API that manages point-in-times in x-pack
basic. Elasticsearch pit (point in time) is a lightweight view into the
state of the data as it existed when initiated. A search request by
default executes against the most recent point in time. In some cases,
it is preferred to perform multiple search requests using the same point
in time. For example, if refreshes happen between search_after requests,
then the results of those requests might not be consistent as changes
happening between searches are only visible to the more recent point in
time.

A point in time must be opened before being used in search requests. The
`keep_alive` parameter tells Elasticsearch how long it should keep a
point in time around.

```
POST /my_index/_pit?keep_alive=1m
```

The response from the above request includes a `id`, which should be
passed to the `id` of the `pit` parameter of search requests.

```
POST /_search
{
    "query": {
        "match" : {
            "title" : "elasticsearch"
        }
    },
    "pit": {
            "id":  "46ToAwMDaWR4BXV1aWQxAgZub2RlXzEAAAAAAAAAAAEBYQNpZHkFdXVpZDIrBm5vZGVfMwAAAAAAAAAAKgFjA2lkeQV1dWlkMioGbm9kZV8yAAAAAAAAAAAMAWICBXV1aWQyAAAFdXVpZDEAAQltYXRjaF9hbGw_gAAAAA==",
            "keep_alive": "1m"
    }
}
```

Point-in-times are automatically closed when the `keep_alive` is
elapsed. However, keeping point-in-times has a cost; hence,
point-in-times should be closed as soon as they are no longer used in
search requests.

```
DELETE /_pit
{
    "id" : "46ToAwMDaWR4BXV1aWQxAgZub2RlXzEAAAAAAAAAAAEBYQNpZHkFdXVpZDIrBm5vZGVfMwAAAAAAAAAAKgFjA2lkeQV1dWlkMioGbm9kZV8yAAAAAAAAAAAMAWIBBXV1aWQyAAA="
}
```

#### Notable works in this change:

- Move the search state to the coordinating node: #52741
- Allow searches with a specific reader context: #53989
- Add the ability to acquire readers in IndexShard: #54966

Luca Cavanna 39e59d6edf Share more query execution code for runtime fields (#62229)
For runtime fields we have written quite some lucene queries that work against runtime values that are the result of the execution of the different script contexts that runtime fields support.

The all (but one) share the same main logic: use a two phase iterator, iterate over all documents, and decide whether the current doc matches or not based on what the script returns. I went ahead and shared this bit of code in the base class for all queries on top of runtime fields.

Remove REST APIs documentation for experimental Searchable Snapshot APIs (#62217) (#62231)
This commit removes the documentation for some specific Searchable Snapshot REST APIs:
- clear cache
- searchable snapshot stats
- repository stats

backed indices but we expect them to be removed in the future or to appear in
a different form.

Change yaml test suite testcase to automatically delete all data streams after each yaml test (#62214)
Backporting #62205 to 7.x branch.

This is similar to what happens for indices. Initially we decided to let each test cleanup the
data streams it created.

The reason behind this was that client yaml test runners would need to be modified to do this too and
because data steams were new, we waited with that and let each test cleanup the data stream it created.
However we sometimes have very hard to debug test failures, because many tests fail because another test
failed mid way and didn't clean up the data streams it created. Given that and data streams exist in
the code base for a while now, we should automatically delete all data streams after each yaml test.

David Roberts 969a1c558b [ML] Include the "properties" layer in find_file_structure mappings (#62158)
Previously the "mappings" field of the response from the
find_file_structure endpoint was not a drop-in for the
mappings format of the create index endpoint - the
"properties" layer was missing.  The reason for omitting
it initially was that the assumption was that the
find_file_structure endpoint would only ever return very
simple mappings without any nested objects.  However,
this will not be true in the future, as we will improve
mappings detection for complex JSON objects.  As a first
step it makes sense to move the returned mappings closer
to the standard format.

This is a small building block towards fixing #55616

* plugins/repository-hdfs - kept the integTest task, but use `rest-test` plugin to define the task

This prevent `keyword` valued runtime scripts from emitting too many

allocate a ton of memory with the script by sticking it into a tight

1. I don't want to rely on them out of sheer paranoia
2. They don't really kick in when the script uses callbacks like we do

This implies that the tree has no features. In this case,

Luca Cavanna b680d3fb29 Async search: don't track fetch failures (#62111)
Fetch failures are currently tracked byy AsyncSearchTask like ordinary shard failures. Though they should be treated differently or they end up causing weird scenarios like total=num_shards and successful=num_shards as the query phase ran fine yet the failed count would reflect the number of shards where fetch failed.

Given that partial results only include aggs for now and are complete even if fetch fails, we can ignore fetch failures in async search, as they will be anyways included in the response. They are in fact either received as a failure when all shards fail during fetch, or as part of the final response when only some shards fail during fetch.

Also, we streamline the way the description is printed out by SearchTask so that it does not get forgotten in the future.

Rename runtime_script field type to runtime (#62034)
We've had some discussions around the user experience when using runtime fields. Although we do plan on having multiple runtime fields implementation (e.g. grok, lookup etc.) which could be exposed as different field types, we decided to expose all runtime fields under the same `runtime` type. At the moment, the only implementation will be through scripts, hence a `script` must be specified. In the future, there will be other ways to generate values for runtime fields besides scripts.

This translates also to renaming the RuntimeScriptFieldMapper class to RuntimeFieldMapper .

Improve reduction of terms aggregations (#61779) (#62028)
Today, the terms aggregation reduces multiple aggregations at once using a map
to group same buckets together. This operation can be costly since it requires
to lookup every bucket in a global map with no particular order.
This commit changes how term buckets are sorted by shards and partial reduces in
order to be able to reduce results using a merge-sort strategy.
For bwc, results are merged with the legacy code if any of the aggregations use
a different sort (if it was returned by a node in prior versions).

Move data stream yaml tests to xpack plugin module. (#62032)
Backport of #61998 to 7.x branch.

Moving the data stream yaml tests to xpack plugin module has the following benefits:
* The tests are ran both with security enabled (as part of xpack/plugin integTest)
  and disabled (as part of xpack/plugin/data-stream/qa/rest integTest).
* and running the tests in mixed cluster qa environment.

Add support for runtime fields (#61776)
This commit includes the work that has been done on the runtime fields feature branch until now. The high level tasks are listed in #59332. The tasks that have not yet been completed can be worked on after merging the feature branch.

We are adding a new x-pack plugin called runtime-fields that plugs in a custom mapper which allows to define runtime fields based on a script.
The changes included in this commit that were made outside of the x-pack/plugin/runtime-fields directory are minimal and revolve around 1) making the ScriptService available while parsing index mappings so that the scripts associated to runtime fields can be compiled 2) sharing code to manipulate ranges etc. as it can be reused in runtime fields.

Simplifies allocation for snapshot-backed shards by always making the recovery source "from snapshot" for those
snapshot-backed shards (instead of "recover from local or from empty store"). Also let's the balancer pick a node which
to allocate the snapshot-backed shard to (which takes number of shards on each node into account unlike the current
implementation which just picks whatever node we are allowed to allocate to, with no notion of "balancing" at all).

Reduce locking in prewarming (#61837) (#61967)
During prewarming of a Lucene file a CacheFile is acquired and 
then locked for the duration of the prewarming, ie locked until all 
the part of the file has been downloaded and written to cache on 
disk. The locking (executed with CacheFile#fileLock()) is here to 
prevent the cache file to be evicted while it is prewarming.

But holding the lock may take a while for large files, specially since
 restoring snapshot files now respects the 
indices.recovery.max_bytes_per_sec setting of 40mb (#58658), 
and this can have bad consequences like preventing the CacheFile 
to be evicted, opened or closed. In manual tests this bug slow 
downs various requests like mounting a new searchable snapshot
 index or deleting an existing one that is still prewarming.

This commit reduces the time the lock is held during prewarming so
 that the read lock is only required when actively writing to the CacheFile.

[7.x][ML] Add incremental id during data frame analytics reindexing (#61943) (#61971)
Previously, we added a copy of the `_id` during reindexing and sorted
the destination index on that. This allowed us to traverse the docs in the
destination index in a stable order multiple times and with efficiency.
However, the destination index being sorted means we cannot have `nested`
typed fields. This is a problem as it does not allow us to provide
a good experience with our evaluate API when it comes to computing
metrics for specific classes, features, etc.

This commit changes the approach in order to result to a destination
index that allows nested fields.

Instead of adding a copy of the `_id` field, we now add an incremental
id that we can use to traverse the docs in a stable order. We also
ensure we always assign the same incremental id to the same doc from
the source indices by sorting on `_seq_no` during reindexing. That
in combination with the reindexing API using scroll gives us a stable
order as scroll uses the (`_index`, `_doc`, shard_id) tuple to resolve ties.

The extractor now does not need to scroll. Instead we sort on the incremental
id and we do ranged searches to avoid the sort-all-docs overhead.

Finally, the `TestDocsIterator` is simply changed to search_after the incremental id.

With these changes data frame analytics jobs do not use scroll at any part.

Having all these in place, the commit adds the `nested` types to the necessary
fields of `classification` and `regression` analyses results.

Add DEBUG logging for undefined role mapping field (#61887)
A role mapping with the following content:

    "rules": { "field": { "userid" : "admin" } }

will never match because `userid` is not a valid field. The correct
field is `username`.

This change adds DEBUG logging when an undefined field is referenced.

The choice to use DEBUG rather than INFO/WARN is that the set of
fields is partially dynamic (e.g. the `metadata.*` fields), so
it may be perfectly reasonable to check a field that is not defined
for that user. For example this rule:

    "rules": { "field": { "metadata.ranking" : "A" } }

would generate a log message for an unranked user, which would
erroneously suggest that such a rule is an error.
This DEBUG logging will assist in diagnosing problems, without
introducing that confusion.

Simplify adding plugins and modules to testclusters (#61886)
There are currently half a dozen ways to add plugins and modules for
test clusters to use. All of them require the calling project to peek
into the plugin or module they want to use to grab its bundlePlugin
task, and then both depend on that task, as well as extract the archive
path the task will produce. This creates cross project dependencies that
are difficult to detect, and if the dependent plugin/module has not yet
been configured, the build will fail because the task does not yet
exist.

This commit makes the plugin and module methods for testclusters
symmetetric, and simply adding a file provider directly, or a project
path that will produce the plugin/module zip. Internally this new
variant uses normal configuration/dependencies across projects to get
the zip artifact. It also has the added benefit of no longer needing the
caller to add to the test task a dependsOn for bundlePlugin task.

Fix data stream wildcard resolution bug in eql search api.(#61910)
Backport of #61904 to 7.x branch.

The eql search api redirects to the search api. For this reason the eql
search api could work with concrete data stream names. However if security
is enabled and a data stream name snippet with a wildcard was used then
it could not resolve this expressions. This is because the EqlSearchRequest
class didn't overwrite the `includeDataStreams()` method. This pr fixes this,
so that the security layer can properly expand data stream name wildcard
expressions for the eql search api.

This commit also moves the eql data stream test to xpack rest tests,
so that the test runs with security enabled. This is required to reproduce
the bug.

[7.x][ML] Update reindexing task progress before persisting job progress (#61868) (#61875)
This fixes a bug introduced by #61782. In that PR I thought I could
simplify the persistence of progress by using the progress straight
from the stats holder in the task instead of calling the get
stats action. However, I overlooked that it is then possible to
have stale progress for the reindexing task as that is only updated
when the get stats API is called.

In this commit this is fixed by updating reindexing task progress
before persisting the job progress. This seems to be much more
lightweight than calling the get stats request.

@ywangd made an awesome analysis on why this test is failing, over
at https://github.com/elastic/elasticsearch/issues/55816#issuecomment-620913282

This change makes it so that we use the same client to perform a
refresh of a token, as we use to subsequently attempt to authenticate
with the refreshed token. This ensures the tests are failing and is
a good approximation of how we expect the same client doing the
refresh, to also perform the subsequent authentication in real life
uses.

The errors we were seeing from users have disappeared after #55114
so we deem our behavior safe.

Prevent snapshots to be mounted as system indices (#61517) (#61727)
System indices can be snapshotted and are therefore potential candidates 
to be mounted as searchable snapshot indices. As of today nothing 
prevents a snapshot to be mounted under an index name starting with . 
and this can lead to conflicting situations because searchable snapshot 
indices are read-only and Elasticsearch expects some system indices 
to be writable; because searchable snapshot indices will soon use an 
internal system index (#60522) to speed up recoveries and we should
prevent the system index to be itself a searchable snapshot index 
(leading to some deadlock situation for recovery).

This commit introduces a changes to prevent snapshots to be mounted 
as a system index.

[7.x] Allocate newly created indices on data_hot tier nodes (#61342) (#61650)
This commit adds the functionality to allocate newly created indices on nodes in the "hot" tier by
default when they are created.

This does not break existing behavior, as nodes with the `data` role are considered to be part of
the hot tier. Users that separate their deployments by using the `data_hot` (and `data_warm`,
`data_cold`, `data_frozen`) roles will have their data allocated on the hot tier nodes now by
default.

This change is a little more complicated than changing the default value for
`index.routing.allocation.include._tier` from null to "data_hot". Instead, this adds the ability to
have a plugin inject a setting into the builder for a newly created index. This has the benefit of
allowing this setting to be visible as part of the settings when retrieving the index, for example:

```
// Create an index
PUT /eggplant

// Get an index
GET /eggplant?flat_settings
```

Returns the default settings now of:

```json
{
  "eggplant" : {
    "aliases" : { },
    "mappings" : { },
    "settings" : {
      "index.creation_date" : "1597855465598",
      "index.number_of_replicas" : "1",
      "index.number_of_shards" : "1",
      "index.provided_name" : "eggplant",
      "index.routing.allocation.include._tier" : "data_hot",
      "index.uuid" : "6ySG78s9RWGystRipoBFCA",
      "index.version.created" : "8000099"
    }
  }
}
```

After the initial setting of this setting, it can be treated like any other index level setting.

This new setting is *not* set on a new index if any of the following is true:

- The index is created with an `index.routing.allocation.include.<anything>` setting
- The index is created with an `index.routing.allocation.exclude.<anything>` setting
- The index is created with an `index.routing.allocation.require.<anything>` setting
- The index is created with a null `index.routing.allocation.include._tier` value
- The index was created from an existing source metadata (shrink, clone, split, etc)

if the index access control before the query and fetch phases differs
from when the scroll context is created, is too strict, leading to spurious
warning log messages.
The check verifies instance equality but this assumes that the fetch
phase is executed in the same thread context as the scroll context
validation. However, this is not true if the scroll search is executed
cross-cluster, and even for local scroll searches it is an unfounded assumption.

The check is hence reduced to a null check for the index access.
The fact that the access control is suitable given the indices that
are actually accessed (by the scroll) will be done in a follow-up,
after we better regulate the creation of index access controls in general.

Pass SearchLookup supplier through to fielddataBuilder (#61430) (#61638)
Runtime fields need to have a SearchLookup available, when building their fielddata implementations, so that they can look up other fields, runtime or not.

To achieve that, we add a Supplier<SearchLookup> argument to the existing MappedFieldType#fielddataBuilder method.

As we introduce the ability to look up other fields while building fielddata for mapped fields, we implicitly add the ability for a field to require other fields. This requires some protection mechanism that detects dependency cycles to prevent stack overflow errors.

With this commit we also introduce detection for cycles, as well as a limit on the depth of the references for a runtime field. Note that we also plan on introducing cycles detection at compile time, so the runtime cycles detection is a last resort to prevent stack overflow errors but we hope that we can reject runtime fields from being registered in the mappings when they create a cycle in their definition.

Note that this commit does not introduce any production implementation of runtime fields, but is rather a pre-requisite to merge the runtime fields feature branch.

This is a breaking change for MapperPlugins that plug in a mapper, as the signature of MappedFieldType#fielddataBuilder changes from taking a single argument (the index name), to also accept a Supplier<SearchLookup>.

Relates to #59332

David Turner f6055dc9b2 Suppress noisy SSL exceptions (#61359)
If a TLS-protected connection closes unexpectedly then today we often
emit a `WARN` log, typically one of the following:

    io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: Insufficient buffer remaining for AEAD cipher fragment (2). Needs to be more than tag size (16)

    io.netty.handler.codec.DecoderException: javax.net.ssl.SSLException: Received close_notify during handshake

We typically only report unexpectedly-closed connections at `DEBUG`
level, but these two messages don't follow that rule and generate a lot
of noise as a result. This commit adjusts the logging to report these
two exceptions at `DEBUG` level only.

David Turner b866aaf81c Use int for number of parts in blob store (#61618)
Today we use `long` to represent the number of parts of a blob. There's
no need for this extra range, it forces us to do some casting elsewhere,
and indeed when snapshotting we iterate over the parts using an `int`
which would be an infinite loop in case of overflow anyway:

    for (int i = 0; i < fileInfo.numberOfParts(); i++) {

This commit changes the representation of the number of parts of a blob
to an `int`.

Introduce cache index for searchable snapshots (#61595)
If a searchable snapshot shard fails (e.g. its node leaves the cluster)
we want to be able to start it up again on a different node as quickly
as possible to avoid unnecessarily blocking or failing searches. It
isn't feasible to fully restore such shards in an acceptably short time.
In particular we would like to be able to deal with the `can_match`
phase of a search ASAP so that we can skip unnecessary waiting on shards
that may still be warming up but which are not required for the search.

This commit solves this problem by introducing a system index that holds
much of the data required to start a shard. Today(*) this means it holds
the contents of every file with size <8kB, and the first 4kB of every
other file in the shard. This system index acts as a second-level cache,
behind the first-level node-local disk cache but in front of the blob
store itself. Reading chunks from the index is slower than reading them
directly from disk, but faster than reading them from the blob store,
and is also replicated and accessible to all nodes in the cluster.

(*) the exact heuristics for what we should put into the system index
are still under investigation and may change in future.

This second-level cache is populated when we attempt to read a chunk
which is missing from both levels of cache and must therefore be read
from the blob store.

We also introduce `SearchableSnapshotsBlobStoreCacheIntegTests` which
verify that we do not hit the blob store more than necessary when
starting up a shard that we've seen before, whether due to a node
restart or because a snapshot was mounted multiple times.

[7.x][ML] Recover data frame extraction search from latest sort key (#61544) (#61572)
If a search failure occurs during data frame extraction we catch
the error and retry once. However, we retry another search that is
identical to the first one. This means we will re-fetch any docs
that were already processed. This may result either to training
a model using duplicate data or in the case of outlier detection to
an error message that the process received more records than it
expected.

This commit fixes this issue by tracking the latest doc's sort key
and then using that in a range query in case we restart the search
due to a failure.

EQL: Replace SearchHit in response with Event (#61428) (#61522)
The building block of the eql response is currently the SearchHit. This
is a problem since it is tied to an actual search, and thus has scoring,
highlighting, shard information and a lot of other things that are not
relevant for EQL.
This becomes a problem when doing sequence queries since the response is
not generated from one search query and thus there are no SearchHits to
speak of.
Emulating one is not just conceptually incorrect but also problematic
since most of the data is missed or made-up.

As such this PR introduces a simple class, Event, that maps nicely to
the terminology while hiding the ES internals (the use of SearchHit or
GetResult/GetResponse depending on the API used).

Correct how field retrieval handles multifields and copy_to. (#61391)
Before when a value was copied to a field through a parent field or `copy_to`,
we parsed it using the `FieldMapper` from the source field. Instead we should
parse it using the target `FieldMapper`. This ensures that we apply the
appropriate mapping type and options to the copied value.

To implement the fix cleanly, this PR refactors the value parsing strategy. Now
instead of looking up values directly, field mappers produce a helper object
`ValueFetcher`. The value fetchers are responsible for almost all aspects of
fetching, including looking up the right paths in the _source.

The PR is fairly big but each commit can be reviewed individually.

Fixes #61033.

[ML] Ensure annotations index mappings are up to date (#61142)
When the ML annotations index was first added, only the
ML UI wrote to it, so the code to create it was designed
with this in mind.  Now the ML backend also creates
annotations, and those mappings can change between
versions.

In this change:

1. The code that runs on the master node to create the
   annotations index if it doesn't exist but another ML
   index does also now ensures the mappings are up-to-date.
   This is good enough for the ML UI's use of the
   annotations index, because the upgrade order rules say
   that the whole Elasticsearch cluster must be upgraded
   prior to Kibana, so the master node should be on the
   newer version before Kibana tries to write an
   annotation with the new fields.
2. We now also check whether the annotations index exists
   with the correct mappings before starting an autodetect
   process on a node.  This is necessary because ML nodes
   can be upgraded before the master node, so could write
   an annotation with the new fields before the master node
   knows about the new fields.

But, when opening a job, we attempt to clear out the jobs finished_time. If the job configuration has adjusted between the versions (i.e. added a new field), it will dynamically update the .ml-config index.

We should instead manually change the mapping to be the updated version.

frozen node).

This also includes a custom `AllocationDecider` that allows the user to configure the following
settings on a cluster level:
- `cluster.routing.allocation.require._tier`
- `cluster.routing.allocation.include._tier`
- `cluster.routing.allocation.exclude._tier`

And in index settings:
- `index.routing.allocation.require._tier`
- `index.routing.allocation.include._tier`
- `index.routing.allocation.exclude._tier`

ILM: add frozen phase (#60983) (#61035)
This adds a frozen phase to ILM that will allow the execution of the
set_priority, unfollow, allocate, freeze and searchable_snapshot actions.

The frozen phase will be executed after the cold and before the delete phase.

Yannick Welsch 6644f2283d Do not access snapshot repo on dedicated voting-only master node (#61016)
Today a snapshot repository verification ensures that all master-eligible and data nodes have write access to the
snapshot repository (and can see each other's data) since taking a snapshot requires data nodes and the currently
elected master to write to the repository. However, a dedicated voting-only master-eligible node is not a data node and
will never be the elected master so we should not require it to have write access to the repository.

[ML] adjusting inference processor to support foreach usage (#60915) (#61022)
`foreach` processors store information within the `_ingest` metadata object.

This commit adds the contents of the `_ingest` metadata (if it is not empty).

And will append new inference results if the result field already exists.

This allows a `foreach` to execute and multiple inference results being written to the same result field.

Search fix: query_string regex/wildcard searches not working on wildcard fields (#60959) (#61010)
The Query string parser was not delegating the construction of wildcard/regex queries to the underlying field type.

Simplify and Speed up some Compression Usage (#60953) (#61008)
Use thread-local buffers and deflater and inflater instances to speed up
compressing and decompressing from in-memory bytes.
Not manually invoking `end()` on these should be safe since their off-heap memory
will eventually be reclaimed by the finalizer thread which should not be an issue for thread-locals
that are not instantiated at a high frequency.
This significantly reduces the amount of byte copying and object creation relative to the previous approach
which had to create a fresh temporary buffer (that was then resized multiple times during operations), copied
bytes out of that buffer to a freshly allocated `byte[]`, used 4k stream buffers needlessly when working with
bytes that are already in arrays (`writeTo` handles efficient writing to the compression logic now) etc.

Relates #57284 which should be helped by this change to some degree.
Also, I expect this change to speed up mapping/template updates a little as those make heavy use of these
code paths.

This commit removes the ability to test the top level result of an aggregator
before it runs the final reduce. All aggregator tests that use AggregatorTestCase#search
are rewritten with AggregatorTestCase#searchAndReduce in order to ensure that we test

that could be different.

Add recovery state tracking for Searchable Snapshots (#60751)
This pull request adds recovery state tracking for Searchable Snapshots.

In order to track recoveries for searchable snapshot backed indices, this pull
request adds a new type of RecoveryState.
This newRecoveryState instance is able to deal with the
small differences that arise during Searchable snapshots recoveries.

Those differences can be summarized as follows:

-  The Directory implementation that's provided by SearchableSnapshots mark the
    snapshot files as reused during recovery. In order to keep track of the
    recovery process as the cache is pre-warmed, those files shouldn't be marked
    as reused.
 - Once the shard is created, the cache starts its pre-warming phase, meaning that
    we should keep track of those downloads during that process and tie the recovery
    to this pre-warming phase. The shard is considered recovered once this pre-warming
    phase has finished.

Move mapper validation to the mappers themselves (#60072) (#60649)
Currently, validation of mappers (checking that cross-references are correct, limits on
field name lengths and object depths, multiple definitions, etc) is performed by the
MapperService. This means that any mapper-specific validation, for example that done
on the CompletionFieldMapper, needs to be called specifically from core server code,
and so we can't add validation to mappers that live in plugins.

This commit reworks the validation framework so that mapper-specific validation is
done on the Mapper itself. Mapper gets a new `validate(MappingLookup)`
method (already present on `MetadataFieldMapper` and now pulled up to the parent
interface), which is called from a new `DocumentMapper.validate()` method. All
the validation code currently living on `MapperService` moves either to individual
mapper implementations (FieldAliasMapper, CompletionFieldMapper) or into
`MappingLookup`, an altered `DocumentFieldMappers` which now knows about
object fields and can check for duplicate definitions, or into DocumentMapper
which handles soft limit checks.

SQL: Add option to provide the delimiter for the CSV format (#59907) (#60420)
* SQL: Add option to provide the delimiter for the CSV format (#59907)

* Add option to provide the delimiter to the CSV fmt

This adds the option to provide the desired character as the separator
for the CSV format (the default remains comma).
A set of characters are excluded though - like CR, LF, `"` - to avoid
slipping onto the CSV-dialects slope. The tab is also forbidden, the
user needs to choose the "tsv" format explicitely.

Update the doc to make it clear that the textual CSV, TSV and TXT
formats pass the cursor back to the user through the Cursor HTTP header.

(cherry picked from commit 3a8b00cc7480f7ada57fcea3cbac957facac08fc)

* Java8 fixes

- replace Set#of();
- URLDecoder#decode() requires a string (vs a charset) as 2nd arg.

Add compatibility testing for JDBC driver (#60409)
This commit adds compatibility testing of our JDBC driver against
different Elasticsearch versions. Although we are really testing the
forwards compatibility nature of the JDBC driver we model the testing
the same as we do existing BWC tests, that is, with the current branch
fetching the earlier versions of the artifact that is to be tested. In
this case, that's the JDBC driver itself.

Because the tests include the JDBC driver jar on it's classpath we had
to change the packaging of the driver jar in order to avoid jarhell and
other conflicting dependency issues when using an old JDBC driver with
later branches. For this we simply relocate all driver dependencies in
the shadow jar under a "shadowed" package. This allows the JDBC driver
to use the correct version of Elasticsearch libs classes, while the
tests themselves use their versions. Since this required a change to the
driver jar compatibility testing can only go back as far as that version
which at the time of this commit is 7.8.1.

[ML] Take more care that memory estimation uses unique named pipes (#60405)
Prior to this change ML memory estimation processes for a
given job would always use the same named pipe names.  This
would often cause one of the processes to fail.

This change avoids this risk by adding an incrementing counter
value into the named pipe names used for memory estimation
processes.

Increase Timeouts in SLMBlockingIntegTests (#60356) (#60403)
The retention run goes through a number of steps and can randomly take more than 10s.
=> increased timeout to 30s like we did in other spots in this test

Also, noticed that we had a hard wait of 10s in this test, removed it and adjusted following
busy assert in a way that can deal with a missing snapshot (from when the assert runs before
the snapshot was put into the CS).

[ML] always write prediction_[score|probability] for classification inference (#60335) (#60397)
In order to unify model inference and analytics results we
need to write the same fields.

prediction_probability and prediction_score are now written
for inference calls against classification models.

Allow CCR on nodes with legacy roles only (#60093)
CCR will stop functioning if the master node is on 7.8, but data nodes 
are before that version because the master node considers that all data
nodes do not have the remote cluster client role. This commit allows CCR
work on data nodes with legacy roles only.

[ML] require alias when indexing to an alias that should be created (#60315) (#60394)
This sets up all indexing to one of our write aliases to require it actually be an alias.

This allows failures scenarios to be captured quickly, loudly, and then potentially recovered.

The JDK bug (https://bugs.openjdk.java.net/browse/JDK-8246193) is fixed since b26.
The tests can be unmuted since we are already using b33. However the same bug is now
affecting jdk 8u262, which is the base for current Zulu jdk 8.48. This PR mute the tests
for this specific jdk version.
