> When work for HBASE-17178, I found there are not a metric for the overall
> duration of region in transition. When move a region form A to B, the
> transformation of region state is PENDING_CLOSE => CLOSING => CLOSED =>
> PENDING_OPEN => OPENING => OPENED. When transform old region state to new
> region state, it update the time stamp to current time. So we can't get the
> overall transformation's duration of region in transition. Add a rit duration
> to RegionState for accumulating this metric.
