Description

With coprocessors hooks while put happens we have the provision to create new puts to other tables or regions. These puts can be done with writeToWal as false.
In 0.94 and above the puts are first written to memstore and then to WAL. If any failure in the WAL append or sync the memstore is rollbacked.
Now the problem is that if the put that happens in the main flow fails there is no way to rollback the
puts that happened in the prePut.

We can add coprocessor hooks to like pre/postRoolBackMemStore. Is any one hook enough here?
