Description

After HBASE-7403 we now have two different tools for online and offline merge, and the result produced by the two are different. (the online one works with snapshots, the offline not)

We should remove the offline one, or align it to the online code.
Most of the offline code in HRegion.merge() can be replaced with the one in RegionMergeTransaction, used by the online version.
