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.

* 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.

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.
