> After RM restart, the RM sends a resync response to NMs that heartbeat to it.  Upon receiving
the resync response, the NM kills all containers and re-registers with the RM. The NM should
be changed to not kill the container and instead inform the RM about all currently running
containers including their allocations etc. After the re-register, the NM should send all
pending container completions to the RM as usual.
