> Currently on  master restart if it tries to do processRIT, any region if found on dead
server tries to avoid the nwe assignment so that timeout monitor can take care.
> This case is more prominent if the node is found in RS_ZK_REGION_OPENING state. I think
we can handle this by triggering a new assignment with a new plan.
