The merge policy that was used could lead to unpredictive merges due to the
randomization of `setDeletesPctAllowed`.

Relates #32767

We do not support passphrases on the secure settings storage (the
keystore). Yet, we added support for this in the API layer. This commit
removes this support so that we are not limited in our future options,
or have to make a breaking change.

* HLRC: adding machine learning delete job

* Fixing whitespace

* Moving docs and tests around

* Unifying ml asciidoc file naming convention

This commit disables the automatic `refresh_interval` in order to ensure
that index readers cannot differ between the normal and scroll search.
This issue is related to the 7.5 Lucene upgrade which contains a change that
makes single segment merge more likely to occur (max deletes percentage).

Closes #32682

This removes def from the classes map in PainlessLookup and instead always special 
cases it. This prevents potential calls against the def type that shouldn't be made and 
forces all cases of def throughout Painless code to be special cased.

The docs here incorrectly state that it is okay for a heap dump file to
exist when heap dump path is configured to a fixed filename. This is
incorrect, the JVM will fail to write the heap dump if a heap dump file
already exists at the specified location (see the DumpWriter constructor
DumpWriter::DumpWriter(const char* path) in the JVM source).

[ML] Re-enabling BWC tests

Re-enable BWC tests for ML now that #32816 has been backported to 6.x

The Kibana settings docs that these watches rely on can sometimes
contain no xpack settings. When this is the case, we will end up with a
null pointer exception in the script. We need to guard against in these
scripts so this commit does that.

This commit removes the put privilege API in favor of having a single API to
create and update privileges. If we see the need to have an API like this in
the future we can always add it back.

Add tests for build-tools to make sure example plugins build stand-alone using it.

This will catch issues such as referencing files from the buildSrc directly, breaking external uses of build-tools.

…of the query phase.

Fixes PercolateQueryBuilder#createMultiDocumentSearcher and PercolatorQuerySearchIT.

This commit updated the google-cloud-storage library from version 1.28.0
 to version 1.40.0.

This committ removes the getMetadata() methods from the DateHistoGroupConfig 
and HistoGroupConfig objects. This way the configuration objects do not rely on RollupField.formatMetaField() anymore and do not expose a getMetadata() 
method that is tighlty coupled to the rollup indexer.

This commit adds a hook to AbstractSerializingTestCase to enable
skipping asserting that the x-content of the test instance and an
instance parsed from the x-content of the test instance are the
same. While we usually expect these to be the same, they will not be the
same when exceptions are involved because the x-content there is lossy.

This commit addresses a race condition in the scheduler engine test that
a listener that throws an exception does not cause other listeners to be
skipped. The race here is that we were counting down a latch, and then
throwing an exception yet an assertion that expected the exception to
have been thrown already could execute after the latch was counted down
for the final time but before the exception was thrown and acted upon by
the scheduler engine. This commit addresses this by moving the counting
down of the latch to definitely be after the exception was acted upon by
the scheduler engine.

This reverts commit fdff8f3.

Rewrite test that require Version.V_5 constants.
