Review request for hive.


Updated bug reference to just contain ID instead of the whole URL.


Adds support for query compilation in Hive Server 2 and adds Thrift support for compile/execute

This enables scenarios that need to compile a query before it is executed, e.g. and ODBC driver
that implements SQLPrepare/SQLExecute. This is commonly used for a client that needs metadata
for the query before it is executed.

The patch does not include the auto-generated thrift files per request in the associated JIRA.

This addresses bug HIVE-4321.

Patch does not contain unit tests yet, but we have done some preliminary testing of this through
our ODBC driver.
