> Currently if an action(kill, rebalance) is scheduled with delay, nimbus stores the state in zookeeper and then schedules a delayed event to do final transition. If during this wait time, leader nimbus loses the leadership, when the delayed operation is executed it receives a NotALeaderException which it does not handle causing the nimbus to die. We should catch the exception and ignore it.
