Period task shuts down instance

[Gary Kotton]

When the periodic task ran it detected that an instance was in a conflicting state. That is Nova was under the impression that the instance was running and it was actually not. This was due to an outage on the backend. When the instance was starting up again the period task forced the instance to shutdown.
In some cases this is too extreme and the admin should decide on the action to take.

I don't consider this a high severity issue. If someone is going to mess with things out of band then they can also manually bring them back up since they should know what they are doing.
