Compute global prune upper bound using compaction state of every region
JIRA - https://issues.apache.org/jira/browse/TEPHRA-198
This PR uses the compaction state recorded by co-processors in https://github.com/apache/incubator-tephra/pull/19 to compute the global prune upper bound.
TODO: add some more test cases to test DefaultDataJanitorPlugin.
