Review request for hive and Vaibhav Gumashta.


Bugs: HIVE-5268
    https://issues.apache.org/jira/browse/HIVE-5268


Repository: hive-git


Description
-------

This is a prototype of the patch we have to cleanup resources on HS2 on client disconnects.
This has worked for Hive-10.

An updated patch to handle async query execution and session timeouts is on the way.

Testing
-------

A new test case to test preliminaries.
Manual testing: Start HS2 on a machine and launch a job through JDBC. Before the job is done,
kill the client. The server will cleanup all resources, scratch directory etc at the end of
the query. 


Thanks,
