> RM sends a reboot command to NM in some cases, like when it gets lost and rejoins back. In such a case, NM should act on the command and reboot/reinitalize itself.
> This is akin to TT reinitialize on order from JT. We will need to shutdown all the services properly and reinitialize - this should automatically take care of killing of containers, cleaning up local temporary files etc.
