Review Comment:
@ritegarg @jpisaac Do we need to change the coprocessor priority for this
observer ? The call order for coprocs is based on the priority.
I see that all phoenix coprocs use
QueryServicesOptions.DEFAULT_COPROCESSOR_PRIORITY. E.g. if both
UngroupedAggregateRegionObserver and IndexRegionObserver both define the
preBatchMutate hook, what would be the call order ?
