* Reducing duplication in plugins around ref-counted releasable classes
Both AmazonEc2Reference and AmazonS3Reference duplicate the same logic - a subclass of AbstractRefCounted that also implements Releasable. This change centralizes this paradigm into a AbstractRefCountedReleasable class and supports both clients via generics. It also updates all fetching implementations to use the get() method instead of client()

* Introduce Reference classes for the Closeable and AutoCloseable interfaces
These classes allow you to wrap a reference instance with an onClose runnable that is executed when close() is invoked. Two separate classes are needed because the close() signatures for the two interfaces are different. This change takes the first step to have implementing classes extend from these generic superclasses, before attempting to remove the subclasses entirely. The get() method is also replaced throughout the code base.
Note that there is also a separate Releasable interface that has a similar access pattern, but is implemented separately. This is used in AbstractRefCountedReleasable introduced in a prior commit

* More improvements and refactoring
* Functionality around one-way gating is now moved to a dedicated class - OneWayGate. This replaces duplicate functionality throughout the code.
* The two *Reference classes have been renamed to Gated* since that better represents their functionality
* The AbstractRefCountedReleasable has been improved to no longer be abstract by accepting the shutdown hook. This removes the need for the inner class in ReleasableBytesReference, and further simplifies the plugin subclasses (these could probably be removed entirely).

I previously added a helper that started a MockLogAppender to ensure it
was never added to a Logger before it was started. I subsequently found
the opposite case in RolloverIT.java where the appender was stopped
before it was closed, therefore creating a race where a concurrently
running test in the same JVM could cause a logging failure. This seems
like a really easy mistake to make when writing a test or introduce when
refactoring a test. I've made a change to use try-with-resources to
ensure that proper setup and teardown is done. This should make it much
harder to introduce this particular test bug in the future.
Unfortunately, it did involve touching a lot of files. The changes here
are purely structural to leverage try-with-resources; no testing logic
has been changed.

I observed a test failure with the message
'Attempted to append to non-started appender mock' from an assertion in
`OpenSearchTestCase::after`. I believe this indicates that a
MockLogAppender (which is named "mock") was added as an appender to the
static logging context and some other test in the same JVM happened to
cause a logging statement to hit that appender and cause an error, which
then caused an unrelated test to fail (because they share static state
with the logger). Almost all usages of MockLogAppender start it
immediately after creation. I found a few that did not and fixed those.
I also made a static helper in MockLogAppender to start it upon
creation.

This commit adds an extension point to EngineConfig through EnginePlugin using
a new EngineConfigFactory mechanism. EnginePlugin provides interface methods to
override configurations in EngineConfig. The EngineConfigFactory produces a new
instance of the EngineConfig using these overrides. Defaults are used absent
overridden configurations.
This serves as a mechanism to override Engine configurations (e.g., CodecService,
TranslogConfig) enabling Plugins to have higher fidelity for changing Engine
behavior without having to override the entire Engine (which is only permitted for
a single plugin).

Shard level indexing pressure improves the current Indexing Pressure framework which performs memory accounting at node level and rejects the requests. This takes a step further to have rejections based on the memory accounting at shard level along with other key performance factors like throughput and last successful requests.
**Key features**
- Granular tracking of indexing tasks performance, at every shard level, for each node role i.e. coordinator, primary and replica.
- Smarter rejections by discarding the requests intended only for problematic index or shard, while still allowing others to continue (fairness in rejection).
- Rejections thresholds governed by combination of configurable parameters (such as memory limits on node) and dynamic parameters (such as latency increase, throughput degradation).
- Node level and shard level indexing pressure statistics exposed through stats api.
- Integration of Indexing pressure stats with Plugins for for metric visibility and auto-tuning in future.
- Control knobs to tune to the key performance thresholds which control rejections, to address any specific requirement or issues.
- Control knobs to run the feature in shadow-mode or enforced-mode. In shadow-mode only internal rejection breakdown metrics will be published while no actual rejections will be performed.
The changes were divided into small manageable chunks as part of the following PRs against a feature branch.
- Add Shard Indexing Pressure Settings. #716
- Add Shard Indexing Pressure Tracker. #717
- Refactor IndexingPressure to allow extension. #718
- Add Shard Indexing Pressure Store #838
