Log:
[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.
