Description

Now we only have a getPreviousRegionLocation method which is only used for reverse scan, and it is not perfect as it can not deal with region merge. As we want to add inclusive/exclusive support for start row and end row of a scan, we need to implement general locate to row before/after method for AsyncRegionLocator.
