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.
Diffs

Testing

Full upgrade and downgrade 2x.
Thanks,
