Introduce a javaRestTest source set and task to compliment the yamlRestTest.
javaRestTest differs such that the code is sourced from Java and may have
different dependencies and setup requirements for the test clusters. This also
allows the tests to run in parallel in different cluster instances to prevent any
cross test contamination between the two types of tests.
Included in this PR is all :modules no longer use the integTest task. The tests
are now driven by test, yamlRestTest, javaRestTest, and internalClusterTest.
Since only :modules (and :rest-api-spec) have been converted to yamlRestTest
we can now disable the integTest task if either yamlRestTest or javaRestTest have
been applied. Once all projects are converted, we can delete the integTest task.

Data frame analytics jobs that work with very large datasets
may produce bulk requests that are over the memory limit
for indexing. This commit adds a helper class that bundles
index requests in bulk requests that steer away from the
memory limit. We then use this class both from the results
joiner and the inference runner ensuring data frame analytics
jobs do not generate bulk requests that are too large.
Note the limit was implemented in #58885.

Today if a cluster state observer's listener takes a long time to
process a notification then we log the following rather useless warning
message:
[notifying listener [org.elasticsearch.cluster.ClusterStateObserver$ObserverClusterStateListener@12345678]] took [34567ms]
This commit adds a handful of simple `toString()` implementations in
order to identify the owner of the listener in question.
This change forks the execution of partial
reduces in the coordinating node to the search thread pool.
It also ensures that partial reduces are executed sequentially
and asynchronously in order to limit the memory and cpu that a
single search request can use but also to avoid blocking a
network thread.
If a partial reduce fails with an exception, the search
request is cancelled and the reporting of the error is
delayed to the start of the fetch phase (when the final
reduce is performed). This ensures that we cleanup the
in-flight search requests before returning an error to
the user.

We can save one round of serializing `RepositoryData` on the write path.
This also leads to somewhat better compression because we compress larger chunks
in one go potentially when compared to serializing and compressing in one go.
Also, fixed the double wrapping of collections when copying the repository
data instance via the `withGenId`.
Keepalive options are not well-documented (only in transport section, although also available at http and network level).

keepalives tell any intermediate devices that the connection remains alive, which helps with overzealous firewalls that are
killing idle connections. keepalives are enabled by default in Elasticsearch, but use system defaults for their
configuration, which often times do not have reasonable defaults (e.g. 7200s for TCP_KEEP_IDLE) in the context of
distributed systems such as Elasticsearch.
This PR sets the socket-level keep_alive options for network.tcp.{keep_idle,keep_interval} to 5 minutes on configurations
that support it (>= Java 11 & (MacOS || Linux)) and where the system defaults are set to something higher than 5
minutes. This helps keep the connections alive while not interfering with system defaults or user-specified settings
unless they are deemed to be set too high by providing better out-of-the-box defaults.
Previously the test was asserting the prediction on each document
was close 10.0 from the expected. It turned out that was not enough
as we occasionally saw the test failing by little.
Instead of relaxing that assertion, this commit changes it to
assert the mean prediction error is less than 10.0. This should
reduce the chances of the test failing significantly.

Currently, we do not categorize the operation type in the rejection
exception messsage when we reject an indexing operation for indexing
memory limits. This commit fixes this to ensure that it is identified as
coordinating, primary, or replica.
Currently the logic to rejection replica rejections is evaluate before
adding the additional bytes of the current operation. This means that
the first replica operation which should be rejected will be allowed to
proceed. This commit fixes this logic and adds unit level test to ensure
indexing pressure behavior is correct.
When a document which is distant from existing buckets gets collected, the
`variable_width_histogram` will create a new bucket and then insert it
into the ordered list of buckets.
Currently, a new merge map array is created to move this bucket. This is
very expensive as there might be thousands of buckets.
This PR creates `mergeBuckets(UnaryOperator<Long> mergeMap)` methods in
`BucketsAggregator` and `MergingBucketsDefferingCollector`, and updates
the `variable_width_histogram` to use them. This eliminates the need to
create an entire merge map array for each new bucket and reduces the
memory overhead of the algorithm.

In almost all cases we write uuid named files via this method.
Preemptively deleting just wastes IO ops, we can delete after a write failed
and retry the write to cover the few cases where we actually do an overwrite.
When the job is force-closed or shutting down due to a fatal error we clean
up all cancellable job operations. This includes cancelling the results processor.
However, this means that we might not persist objects that are written from the
process like stats, memory usage, etc.
In hindsight, we do not gain from cancelling the results processor in its
entirety. It makes more sense to skip row results and model chunks but keep
stats and instrumentation about the job as the latter may contain useful information
to understand what happened to the job.

Putting an ingest pipeline used to require that the user calling
it had permission to get nodes info as well as permission to
manage ingest. This was due to an internal implementaton detail
that was not visible to the end user.
This change alters the behaviour so that a user with the
manage_pipeline cluster privilege can put an ingest pipeline
regardless of whether they have the separate privilege to get
nodes info. The internal implementation detail now runs as
the internal _xpack user when security is enabled.

There is a very unlikely but possible test failure in this test.
The `SnapshotsService` continues iterating over queued operations after
resolving the transport listener. This can lead to a situation where the moved
repository data is not picked up when running the delete (even though we
have the concurrent modifications BwC mode activated) concurrently.
I fixed this in the test so that the test still verifies that this setting works.
Technically speaking, one could add logic to the way we queue and execute repo operations
to address this special case. Since this case only comes about with the concurrent modifications
setting enabled (and the setting is gone in master already) I don't really see a reason to improve
the logic here since we should always fail queued up repo operations on concurrent modification for
safety reasons.
It can take more than 10 seconds to auto-follow and create a follow-task
on a slow CI. This commit increases timeout in AutoFollowIT by replacing
assertBusy with assertLongBusy.

Moves the search sort docs from the deprecated 'Request Body Search'
page to a new subpage of 'Run a search'.
No substantive changes were made to the content.
This PR contains the deprecation notice that `create`, `create_doc`, `index` and
`write` ingest privileges do not permit mapping updates in version 8. It also
updates the docs description of said privileges.
This should've been part of #58784
