Description

The new RM needs a handler that can process under replicated Ratis containers and create replication commands. Legacy RM does this in the handleUnderReplicatedContainer method. The new handler should mostly have the same logic as legacy with one notable difference - we don't need to handle mis replication (failure to meet placement policy) because that's a separate case now and should get its own handler.
