Review request for hive.


Changes
-------

I update the diff to address Mark's comments. Thanks, Mark.


Description
-------

To make testing issues like HIVE-3590 convenient, we can implement a UDF to keep hive session
alive for a given time. The patch introduce a new UDF sleep() which does this without introducing
any data/load to cluster.


This addresses bug HIVE-3666.

seconds
