> Support all mutations in BatchOperations to be applied atomically (all or
> none) by locking all rows corresponding to mutations exclusively.
> mutateRows() which uses MultiRowMutationProcessor applies all mutations
> atomically and batchMutate() is non-atomic. To unify code paths, isAtomic()
> attribute can be added to BatchOperations.
