This commit adds an explicit version check for shard indexing pressure
serialization. This is required to not mandate test have the cluster service
initialized while asserting node attributes.

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).

Fixes flakiness for test testReplicaThreadedThroughputDegradationAndRejection.
Reduced the number of threads concurrently executing from the initial range between (100-120) to a new range between (80-100), as the previous range was breaking the node limits set as 10kb, for every execution where number of threads were greater than 110.

* Allow building on FreeBSD
With this set of change, we are able to successfuly run:
```
./gradlew publishToMavenLocal -Dbuild.snapshot=false
```
This step is used in the OpenSearch repository context when building
plugins in the current state of the CI.
While here, reorder OS conditions alphabetically.
Before building, the openjdk14 package was installed and the environment
was adjusted to use it:
```
sudo pkg install openjdk14
export JAVA_HOME=/usr/local/openjdk14/
export PATH=$JAVA_HOME/bin:$PATH
```

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.

This will cause the leader stuck on IO during publication to step down and eventually trigger a leader election.
Issue Description
---
The publication of cluster state is time bound to 30s by a cluster.publish.timeout settings. If this time is reached before the new cluster state is committed, then the cluster state change is rejected and the leader considers itself to have failed. It stands down and starts trying to elect a new master.
There is a bug in leader that when it tries to publish the new cluster state it first tries acquire a lock to flush the new state under a mutex to disk. The same lock is used to cancel the publication on timeout. Below is the state of the timeout scheduler meant to cancel the publication. So essentially if the flushing of cluster state is stuck on IO, so will the cancellation of the publication since both of them share the same mutex. So leader will not step down and effectively block the cluster from making progress.
