> Making SplitTransaction, RegionMergeTransaction limited private is required to support local indexing feature in Phoenix to ensure regions colocation.
> We can ensure region split, regions merge in the coprocessors in few method calls without touching internals like creating zk's, file layout changes or assignments.
> 1) stepsBeforePONR, stepsAfterPONR we can ensure split.
> 2) meta entries can pass through coprocessors to atomically update with the normal split/merge.
> 3) rollback on failure.
