HBASE-18846 Accommodate the hbase-indexer/lily/SEP consumer deploy-type 

Patch to start a standalone RegionServer that register's itself and
optionally stands up Services. Can work w/o a Master in the mix.
Useful testing. Also can be used by hbase-indexer to put up a
Replication sink that extends public-facing APIs w/o need to extend
internals. See JIRA release note for detail.

This patch adds booleans for whether to start Admin and Client Service.
Other refactoring moves all thread and service start into the one fat
location so we can ask to by-pass 'services' if we don't need them.
See JIRA for an example hbase-server.xml that has config to shutdown
WAL, cache, etc.

Adds checks if a service/thread has been setup before going to use it.

Renames the ExecutorService in HRegionServer from service to
executorService.

See JIRA too for example Connection implementation that makes use of
Connection plugin point to receive a replication stream. The default
replication sink catches the incoming replication stream, undoes the
WALEdits and then creates a Table to call a batch with the
edits; up on JIRA, an example Connection plugin (legit, supported)
returns a Table with an overridden batch method where in we do index
inserts returning appropriate results to keep the replication engine
ticking over.

Upsides: an unadulterated RegionServer that will keep replication metrics
and even hosts a web UI if wanted. No hacks. Just ordained configs
shutting down unused services. Injection of the indexing function at a
blessed point with no pollution by hbase internals; only public imports.
No user of Private nor LimitedPrivate classes.
