> Through HBASE-3777, HConnectionManager reuses the connection to HBase servers.
> One challenge, discovered in troubleshooting HBASE-4052, is how we invalidate connection(s)
to server which gets restarted.
> There're at least two ways.
> 1. HConnectionManager utilizes background thread(s) to periodically perform validation
of connections in HBASE_INSTANCES and remove stale connection(s).
> 2. Allow HBaseClient (including HBaseAdmin) to provide feedback to HConnectionManager.
> The solution can be a combination of both of the above.
