The configuration settings "hbase.netty.worker.count" and
"hbase.netty.eventloop.rpcserver.thread.count" appear to duplicate each
other.
Also, formalizes another setting found in NettyEventLoopGroupConfig,
"hbase.netty.nativetransport".
Also, native epoll is not limited to amd64. aarch64 supports it too.

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-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.

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.
