* DISCOVERY: Use Realistic Num. of Min Master Nodes
* With all 3 nodes starting in parallel 2 nodes can win a master election and
start waiting for nodes to join when started in parallel. We wait for 30s on the
rest tests for the cluster health endpoint to show 3 nodes which breaks if
one of the master nodes itself waits for 30s for joining nodes, waiting for 5 seconds
fixes the issue and allows us to run with `minimum master nodes < node count`

Drops the `deprecationLogger` from `AbstractComponent`, moving it to
places where we need it. This saves us from building a bunch of
`DeprecationLogger`s that we don't need.
Relates to #34488
`AbstractComponent` is trouble because its name implies that
*everything* should extend from it. It *is* useful, but maybe too
broadly useful. The things it offers access too, the `Settings` instance
for the entire server and a logger are nice to have around, but not
really needed *everywhere*. The `Settings` instance especially adds a
fair bit of ceremony to testing without any value.
This removes the `nodeName` method from `AbstractComponent` so it is
more clear where we actually need the node name.
* Removed methods are just unused (the exceptions being isGeoPoint() and is
isFloatingPoint() but those could more efficiently be replaced by enum comparisons to simplify the code)
* Remove exceptions aren't thrown
Adds support for the Clear Roles Cache API to the High Level Rest
Client. As part of this a helper class, NodesResponseHeader, has been
added that enables parsing the nodes header from responses that are
node requests.

* Increase the length of randomly generated field
randomAlphaOfLength(2) produced duplicates which led to
com.fasterxml.jackson.core.JsonParseException: Duplicate field

This commit is our first introduction to cross-cluster replication
docs. In this commit, we introduce the cross-cluster replication API
docs. We also add skelton docs for additional content that will be added
in a series of follow-up commits.
In order to remove Streamable from the codebase, Response objects need
to be read using the Writeable.Reader interface which this change
enables. This change enables the use of Writeable.Reader by adding the
`Action#getResponseReader` method. The default implementation simply
uses the existing `newResponse` method and the readFrom method. As
responses are migrated to the Writeable.Reader interface, Action
classes can be updated to throw an UnsupportedOperationException when
`newResponse` is called and override the `getResponseReader` method.

We currently have two different native processes:
autodetect & normalizer. There are plans for introducing
a new process. All these share many things in common.
This commit refactors the processes to extend an
`AbstractNativeProcess` class that encapsulates those
commonalities with the purpose of reusing the code
for new processes in the future.
This commit adds a new ParentJoinAggregator that implements a join using global ordinals
in a way that can be reused by the `children` and the upcoming `parent` aggregation.
This new aggregator is a refactor of the existing ParentToChildrenAggregator with two main changes:
* It uses a dense bit array instead of a long array when the aggregation does not have any parent.
* It uses a single aggregator per bucket if it is nested under another aggregation.
For the latter case we use a `MultiBucketAggregatorWrapper` in the factory in order to ensure that each
instance of the aggregator handles a single bucket. This is more inlined with the strategy we use for other
aggregations like `terms` aggregation for instance since the number of buckets to handle should be low (thanks to the breadth_first strategy).
This change is also required for #34210 which adds the `parent` aggregation in the parent-join module.

Index shard stats for the follower shard are fetched, when a shard follow task is started.
This is needed in order to bootstap the shard follow task with the follower global checkpoint.
Sometimes index shard stats are not available (e.g. during a restart) and
we fail now, while it is very likely that these stats will be available some time later.
Documents the new structured logfile format for auditing
that was introduced by #31931. Most changes herein
are for 6.x . In 7.0 the deprecated format is gone and a
follow-up PR is in order.
The pull request #34338 added strict deprecation mode to the REST tests
and adds the copy_settings param when testing the shrink of an index.
This parameter has been added in 6.4.0 and will be removed in 8.0, so
the test now needs to take care of the old cluster version when adding
the copy_settings param.
* Fix linelength suppressions in index.fielddata
* Some lines that were too long were dead code => Removed them and all code that became dead because of it
* Relates #34884
* Binding to `0` gives us free ports that are assigned sequentially by Linux making collisions much less likely compared to manually finding a free port in a range
* Closes#32208
testClusterFormsByScanningPorts is flaky: sometimes in CI it's not possible to
bind to any of the ports we need to in order for the port scanning to work.
This change removes this test, and #34809 describes a better way to test this
behaviour.
This change ensures the `message` field is always included
in the `field_stats` for the semi-structured text log file
file structure. Previously it was not, as it will almost
certainly contain all distinct values. However, for
consistency in the UI it's useful to include it.
For the assertions in the "testApiNamingConventions" test that check
the API contract, this change adds details of the method that was
being checked, and the intent of the assertion (the API contract)
After discussing on the team's FixItFriday, we concluded that
static final instance variables that are mutable should be lowercased.
Historically, DeprecationLogger was uppercased more frequently than lowercased.
ILM would return a resource-not-found exception when requesting policies
while the IndexLifecycleMetaData is not initialized. The behavior here
should not be as extreme since it is not the user's fault.
This commit changes the behavior so that it succeeds and returns no policies
when no policy names are explicitely specified, otherwise keep the same behavior
of throwing an exception
Adds checks for misbehaving parsers. The checks aren't perfect at all but
they are simple and fast enough that we can do them all the time so
they'll catch most badly behaving parsers.
Closes#34351
