* Improve Painless compilation performance for nested conditionals (#52056)
This PR changes how conditional expression is handled in `PainlessParser`
in a way that avoids the need for backtracking, which led to exponential
compilation times in case of nested conditionals.
The test was added ensures that we can compile deeply nested conditionals.

This change fixes flakiness in `CsvProcessorTests` where source field
can be the same as one of the headers used by tests which messes up
asserts when we check that field is not present after processor run.
Closes#50209
The related issue regarding aggregation queries where some literals
are also selected together with aggregate function has been fixed
with #49570. Add integration tests to verify the behavior.

The main purpose of this commit is to add a single autoscaling REST
endpoint skeleton, for the purpose of starting to build out the build
and testing infrastructure that will surround it. For example, rather
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.
Adds the ability to display docs on permanently unreleased branches,
such as `master` and `7.x`.
Also updates how the autoscaling and EQL docs are included.
Currently, these feature-flag docs would display on any unreleased
branches that contain the changes, such as 7.7.
If the configs are removed (by some horrific means), we should still allow tasks to be cleaned up easily.
Datafeeds and jobs with missing configs are now visible in their respective _stats calls and can be stopped/closed.
* Time parameter includes description

Not all clients support this e.g if the java high level rest client were
to map this it would look like `client.cat().ml().api()` which hinders
discoverability.

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.

Backport of #51867.
Tweak the documentation around configuring the heap size when using
Docker, to state that:
- using `ES_JAVA_OPTS` is the preferred method
- Any `ES_JAVA_OPTS` overrides the defaults in `jvm.options`
- It's possible to bind-mount a custom `jvm.options`
This change ensures that the rewrite of the shard request is executed in the network thread or in the refresh listener when waiting for an active shard. This allows queries that rewrite to match_no_docs to bypass the search thread pool entirely even if the can_match phase was skipped (pre_filter_shard_size > number of shards). Coordinating nodes don't have the ability to create empty responses so this change also ensures that at least one shard creates a full empty response while the other can return null ones. This is needed since creating true empty responses on shards require to create concrete aggregators which would be too costly to build on a network thread. We should move this functionality to aggregation builders in a follow up but that would be a much bigger change.
This change is also important for #49601 since we want to add the ability to use the result of other shards to rewrite the request of subsequent ones. For instance if the first M shards have their top N computed, the top worst document in the global queue can be pass to subsequent shards that can then rewrite to match_no_docs if they can guarantee that they don't have any document better than the provided one.
QueryBuilders that throw exceptions on shards when building the Lucene query
returns the full serialization of the query builder in the exception message.
For large queries that fails to execute due to the max boolean clause, this means
that we keep a reference of these big messages for every shard that participate
in the request. In order to limit the memory needed to hold these query shard
exceptions in the coordinating node, this change removes the query builder
serialization from the shard exception. The query is known by the user so
there should be no need to repeat it on every shard exception. We could also
omit the entire stack trace for known bad request exception but it would deserve
a separate issue/pr.
Closes#51843Closes#48910
When clenaing a shard follow task after an index has been deleted, an
exception can occur submitting the complete persistent task
action. However, this exception message is not logged. This commit
addresses this by including the exception that led to the failure in the
log message.
* Add empty_value parameter to CSV processor
This change adds `empty_value` parameter to the CSV processor.
This value is used to fill empty fields. Fields will be skipped
if this parameter is ommited. This behavior is the same for both
quoted and unquoted fields.
* docs updated
* Fix compilation problem

When the `rare_terms` aggregation contained another aggregation it'd
break them. Most of the time. This happened because the process that it
uses to remove buckets that turn out not to be rare was incorrectly
merging results from multiple leaves. This'd cause array index out of
bounds issues. We didn't catch it in the test because the issue doesn't
happen on the very first bucket. And the tests generated data in such a
way that the first bucket always contained the rare terms. Randomizing
the order of the generated data fixed the test so it caught the issue.
Closes#51020
AutoFollowIT tests are regularly failing on CI because they rely
on how cluster state updates are processed within the integration
clusters. We tried to limit this in #49141 by moving to latches
instead of waiting for assertions to pass but there are still some
places were it still need to wait for the cluster state updates to
be processed and auto-follow stats to be updated.
This commit gives more time to assertBusy() that verifies the
AutoFollowStats (up to 60 seconds) and also always log the
auto-follow stats in case the assertions failed.
Closes#48982

There is an open JDK bug that is causing an assertion in the JDK's
http server to trip if we don't drain the request body before sending response headers.
See https://bugs.openjdk.java.net/browse/JDK-8180754
Working around this issue here by always draining the request at the beginning of the handler.
Fixes#51446
Adds documentation for basic EQL syntax.
Joins, sequences, and other syntax to be added as its supported
in future development.
