Compactions: Use more intelligent priorities for PriorityCompactionQueue
------------------------------------------------------------------------

                 Key: HBASE-3160
                 URL: https://issues.apache.org/jira/browse/HBASE-3160
             Project: HBase
          Issue Type: Improvement
            Reporter: Nicolas Spiegelberg
            Assignee: Nicolas Spiegelberg


One of the problems with the current compaction queue is that we have a very low granularity
on the importance of the various compactions in the queue.  If a StoreFile count exceeds 15
files, only then do we bump via enum change.  We should instead look into more intelligent,
granular priority metrics for choosing the next compaction.
