> 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.
