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

* HBASE-22749 Distributed MOB compactions
- MOB compaction is now handled in-line with per-region compaction on region
servers
- regions with mob data store per-hfile metadata about which mob hfiles are
referenced
- admin requested major compaction will also rewrite MOB files; periodic RS
initiated major compaction will not
- periodically a chore in the master will initiate a major compaction that
will rewrite MOB values to ensure it happens. controlled by
'hbase.mob.compaction.chore.period'. default is weekly
- control how many RS the chore requests major compaction on in parallel
with 'hbase.mob.major.compaction.region.batch.size'. default is as
parallel as possible.
- periodic chore in master will scan backing hfiles from regions to get the
set of referenced mob hfiles and archive those that are no longer
referenced. control period with 'hbase.master.mob.cleaner.period'
- Optionally, RS that are compacting mob files can limit write
amplification by not rewriting values from mob hfiles over a certain size
limit. opt-in by setting 'hbase.mob.compaction.type' to 'optimized'.
control threshold by 'hbase.mob.compactions.max.file.size'.
default is 1GiB
- Should smoothly integrate with existing MOB users via rolling upgrade.
will delay old MOB file cleanup until per-region compaction has managed
to compact each region at least once so that used mob hfile metadata can
be gathered.

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.
