Andrew Purtell updated HBASE-19967:
-----------------------------------
    Description: 
After HBASE-19528 an operator can disable automatic major compaction and more 
intelligently manage major compaction impact on cluster operations with an 
external tool that drives the compaction activity. This tool can be invoked at 
whatever interval is desirable, and can restrict activity by table and column 
family, with given concurrency of regionservers compacting at a given time. 

Add Major Compaction Tool options for off-peak / on-peak hours. Allow for 
definition of "off-peak" as a time range bounded by two points on a 24 hour 
clock, and for two concurrency target for global compaction activity, one for 
the off-peak interval, the other for the remainder.
