    (TEPHRA-214) Tool to debug the state and progress of Invalid List Pruning

    JIRA : https://issues.apache.org/jira/browse/TEPHRA-214
    
    Summary: Introduce a debug tool to fetch data that might help with debugging the status and progress of invalid list transaction list pruning.
    
    Three commands are supported:
    timeregion <timestamp>  ==> Will return TimeRegions at or before timestamp in millis
    idleregions <numOfRegions> ==> Will return numOfRegions regions with lowest pruneUpperBounds. If -1 is provided, all pruneUpperBounds are returned.
    pruneinfo <regionNameAsString> => Will return pruneUpperBound, compactionTimeStamp of the 'regionNameAsString' region.
    
    This tool can be invoked with hbase classpath and tephra jars in the classpath.

> It would be good to get information about what regions are lagging that might be useful to debug why transaction pruning might not be happening. We do print debug information but this method could be invoked on a need-basis outside of the regular pruning operation.
