Summary
-------

Rather than a separate process, it can be advantageous in some situations for each RegionServer
to embed their own ThriftServer. This allows each embedded ThriftServer to short-circuit any
queries that should be executed on the local RS and skip the extra hop. This then enables
the building of fat Thrift clients that cache region locations and avoid extra hops all together.


This addresses bug HBASE-4460.
