When backporting to branch-2 it was discovered that the order of tear
down operations requires the KDC to be torn down first, although on
master branch the original code did not produce the same errors (a NPE
in KDC#stop). Forward port the difference for maintainability.

Add test coverage for SimpleRpcServer.
Improve the way we test both SimpleRpcServer and NettyRpcServer. Use
LoadTestKVGenerator to generate random values with varying sizes between
1000 bytes and 1M bytes, and also to verify them when reading the values
back.
Add secure test coverage for both SimpleRpcServer and NettyRpcServer.

* HBASE-27088 IntegrationLoadTestCommonCrawl async load improvements
- Use an async client and work stealing executor for parallelism during loads.
- Remove the verification read retries, these are not that effective during
replication lag anyway.
- Increase max task attempts because S3 might throttle.
- Implement a side task that exercises Increments by extracting urls from
content and updating a cf that tracks referrer counts. These are not
validated at this time. It could be possible to log the increments, sum
them with a reducer, and then verify the total, but this is left as a
future exercise.

* Sum RPC time for writes (loader) and reads (verifier) and mutation bytes submitted. Expose as job counters.
* Fix an issue with completion chaining
* Pause loading if too many operations are in flight
TestMultiRespectLimits submits a put with an empty value. This appears
to not be what was intended. Instead, use a single byte.

Replace BufferChain#write(channel,int) with a simpler #write(channel)
implementation that does not attempt to "chunk" data to be written. This
method was used exclusively by SimpleRpcServer. The code was unnecessarily
complex and caused short writes when values were large, so was corrected
and simplified. Any difference in performance from this change will be
limited to SimpleRpcServer. Testing under load confirms the fix and does
not show significant regression.
SimpleRpcServer and its related code is now also marked as @Deprecated.

* Take advantage of the fact that OpenTelemetry can read its configuration from environment
variables and make use of this where possible, only falling back to passing properties into the
process launch configuration when it's necessary. DRY up tracing configuration and make it
easier to manage in a container environment.
* Replace `HBASE_TRACE_OPTS`, which used to act as both a feature flag and a baseline for
configuration shared across processes. Instead, use `HBASE_OTEL_TRACING_ENABLED` as a feature
flag, and let configuration reuse be handled via the environment variables that otel supports
naively.
* Add further explanation for how to write your configuration for our different deployment
modes (standalone, pseudo-distributed, fully distributed) and in different environments.

* Fix multiple possible buffer leaks
Motivation:
When using ByteBuf you need to be very careful about releasing it as otherwise you might leak data. There were various places in the code-base where such a leak could happen.
Modifications:
- Fix possible buffer leaks
- Ensure we call touch(...) so its easier to debug buffer leaks
Result:
Fix buffer leaks
* Formatting
* Revert some changes as requested
* revert touch
* Also release checksum and header buffers

A larger IO buffer for absorbing WALCodec writes can improve the compression
ratio of larger values, because the compressor will be given a larger internal
buffer over which there will be more match opportunities. Does not impact the
ability to read existing written files.
Also, reset the BAOS internal buffer on the way out of compress() so potential
large-ish buffers do not linger on the heap longer than necessary.

Support site configuration of the bytebuf allocator that Netty will use for
NettyRpcServer channels. Property name is 'hbase.netty.rpcserver.allocator'.
Default is no value, which is equivalent to "pooled". Valid values are:
- "pooled": use PooledByteBufAllocator
- "unpooled": use UnpooledByteBufAllocator
- "heap": use HeapByteBufAllocator, which is a PooledByteBufAllocator that
preferentially allocates buffers on heap wherever possible
- <class>: If the value is none of the recognized labels, treat it as a class
name implementing org.apache.hbase.thirdparty.io.netty.buffer.ByteBufAllocator.
This allows the user to add a custom implementation, perhaps for debugging.
Also updates ReflectionUtils with a new helper method.
