> 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
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.
