> 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.
