    Compute global prune upper bound using compaction state of every region

    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.

> TEPHRA-35 saves compaction state for every region after a major compaction is done, we
can use this state to compute the global prune upper bound for all regions. The design is
part of TEPHRA-35.
