Description

Currently we have two hooks in the split flow of a region. PreSplit() and postSplit(). But not always these are helpful in case i have a problem in preSplit() or postSplit() i need to do a rollback of the current region or the region that i am handling thro the hooks.

So its better if we have a hook in the rollback code and also one final hook say postCompleteSplit() so that CP can take any corrective action.
Pls do suggest if i can provide a patch for this.
