HIVE-4810 [jira] Refactor exec package
(Gunther Hagleitner via Ashutosh Chauhan)

HIVE-4810

The exec package contains both operators and classes used to execute the job. Moving the latter into a sub package makes the package slightly more manageable and will make it easier to provide a tez-based implementation.

Test Plan: Refactoring
