Review Request 38782: RU cluster in hung state while trying to perform downgrade

-----------------------------------------------------------

Review request for Ambari, Jayush Luniya and Mahadev Konar.


Bugs: AMBARI-123245
    https://issues.apache.org/jira/browse/AMBARI-123245


Repository: ambari


Description
-------

Upgrade/Downgrade still has JPA concurrency problems. It seems like the use of the Parallel thread pool from multiple locations causes ConcurerencyManager in JPA to have problems. For now, leaving the use of Parallel in getStagesInProgress since it seems that this is stable. 

Deprecated Parallel until we can figure out what's really going wrong with it.
