      Description

      There seem to be a few intermediate states that can be added to improve the stability of the NM container state machine.

      For. eg:

      • The REINITIALIZING should probably be split into REINITIALIZING and REINITIALIZING_AWAITING_KILL.
      • Container updates are currently handled in the ContainerScheduler, but it would probably be better to have it plumbed through the container state machine as a new state, say UPDATING and a new container event.

      The plan is to add some extra tests too to try and test every transition.
