[HBASE-9704] Optimize tableExists in HBaseAdmin

Author: manukranthk

Summary:
The Master's tableExists function is more optimal compared to HBaseAdmin's, reverting to use the master's logic.
HBaseAdmin.tableExists previously used to take : ~25s.
Now it takes ~2s.

Test Plan: Tested on calypsohbase001-frc1 and found that it is 10X faster.

[master] Pull async and sync thrift interfaces into two different java interfaces

Author: elliott

Summary:
This pulls the async and sync interfaces apart.  This should allow client implementation to be disconnected from the server.

Currently everything on the server side uses the sync method. All things on the client side will use the thrift async methods.

Test Plan:
mvn clean test

Added unit test to make sure that all of our thrift interfaces are well defined and that sync and async change together.
