Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.
I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler
These files don't *need* `settings` either, but this change is large
enough as is.

When we connect to remote clusters, there may be a few more routers/firewalls in-between compared to when we connect to nodes in the same cluster. We've experienced cases where firewalls drop connections completely and keep-alives seem not to be enough, or they are not properly configured. With this commit we allow to enable application-level pings specifically from CCS nodes to the selected remote nodes through the new setting `cluster.remote.${clusterAlias}.transport.ping_schedule`. The new setting is similar `transport.ping_schedule` but it does not affect intra-cluster communication, pings are only sent to specific remote cluster when specifically enabled, as they are disabled by default.

Drops the `Settings` member from `AbstractComponent`, moving it from the
base class on to the classes that use it. For the most part this is a
mechanical change that doesn't drop `Settings` accesses. The one
exception to this is naming threads where it switches from an invocation
that passes `Settings` and extracts the node name to one that explicitly
passes the node name.
This change doesn't drop the `Settings` argument from
`AbstractComponent`'s ctor because this change is big enough as is.
We'll do that in a follow up change.
This commit filters out usage of deprecated tzs by tests. These are
tested separately and should not require checking for warnings on any
test using random timezones.

This commit adds a new single value metric aggregation that calculates
the statistic called median absolute deviation, which is a measure of
variability that works on more types of data than standard deviation
Our calculation of MAD is approximated using t-digests. In the collect
phase, we collect each value visited into a t-digest. In the reduce
phase, we merge all value t-digests, then create a t-digest of
deviations using the first t-digest's median and centroids
Bulk Request in High level rest client should be consistent with what is
possible in Rest API, therefore should support global parameters. Global
parameters are passed in URL in Rest API.
Some parameters are mandatory - index, type - and would fail validation
if not provided before before the bulk is executed.
Optional parameters - routing, pipeline.
The usage of these should be consistent across sync/async execution,
bulk processor and BulkRequestBuilder

Deprecates `_source_include` and `_source_exclude` url parameters
in favor of `_source_inclues` and `_source_excludes` because those
are consistent with the rest of Elasticsearch's APIs.

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
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.

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.

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.
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.
This is related to #30876. The AbstractSimpleTransportTestCase initiates
many tcp connections. There are normally over 1,000 connections in
TIME_WAIT at the end of the test. This is because every test opens at
least two different transports that connect to each other with 13
channel connection profiles. This commit modifies the default
connection profile used by this test to 6. One connection for each
type, except for REG which gets 2 connections.

The check for null argument is already done in `splitStringByCommaToArray`, hence it can be removed, which allows us to remove the whole splitScrollIds private method.
With this change, we apply the common test config automatically to all
newly created tasks instead of opting in specifically.
For plugin authors using the plugin externally this means that the
configuration will be applied to their RandomizedTestingTasks as well.
The purpose of the task is to simplify setup and make it easier to
change projects that use the `test` task but actually run integration
tests to use a task called `integTest` for clarity, but also because
we may want to configure and run them differently.
E.x. using different levels of concurrency.
Access to special variables _source and _fields were accidentally
removed in recent refactorings. This commit adds them back, along with a
test.

In a future major version, we will be introducing a soft limit on the
number of shards in a cluster based on the number of nodes in the
cluster. This limit will be configurable, and checked on operations
which create or open shards and issue a warning if the operation would
take the cluster over the limit.
There is an option to enable strict enforcement of the limit, which
turns the warnings into errors. In a future release, the option will be
removed and strict enforcement will be the default (and only) behavior.
- Restrict visibility of Aggregators and Factories
- Move PipelineAggregatorBuilders up a level so it is consistent with
AggregatorBuilders
- Checkstyle line length fixes for a few classes
- Minor odds/ends (swapping to method references, formatting, etc)
This commit introduces two corrections to the way simulate?verbose
handles conditionals on processors.
1) Prior to this change when executing simulate?verbose for
processors with conditionals that evaluate to false, that processor
would still be displayed in the result set. What was displayed was
correct, such that no changes to the document occurred. However, if the
conditional evaluates to false, the processor should not even be
displayed.
2) Prior to this change when executing simulate?verbose for
pipeline processors with conditionals, the individual steps would no
longer be displayed. Commit e37e5df addressed the issue, but
failed account for a conditional on the pipeline processor. Since
a pipeline processor can introduce cycles and is effectively a
single processor that encapsulates multiple other processors that
are potentially guarded by a single conditional, special handling is
needed to for pipeline and conditional pipeline processors.
We should delete a job by directly talking to the allocated
task and telling it to shutdown. Today we shut down a job
via the persistent task framework. This is not ideal because,
while the job has been removed from the persistent task
CS, the allocated task continues to live until it gets the
shutdown message.
This means a user can delete a job, immediately delete
the rollup index, and then see new documents appear in
the just-deleted index. This happens because the indexer
in the allocated task is still running and indexes a few
more documents before getting the shutdown command.
In this PR, the transport action is changed to a TransportTasksAction,
and we invoke onCancelled() directly on the matching job.
The race condition still exists after this PR (albeit less likely),
but this was a precursor to fixing the issue and a self-contained
chunk of code. A second PR will followup to fix the race itself.
