Artom Lifshitz a90fe19512 Avoid error 500 on shelve task_state race ... When shelving a server and saving its new SHELVING task state, we expect the current task state to be None and do not handle any UnexpectedTaskStateError exceptions that the database layer may throw at us. In those cases, we return an error 500 to the user, when in actuality an error 409 conflict would be more appropriate. This patch makes the API layer handle UnexpectedTaskStateError exceptions and return a 409 to the user. NOTE(artom) Conflict in imports in nova/tests/unit/api/openstack/compute/test_shelve.py due to using oslo's uuidsentinel as of 8e1ca5bf34 in stein.
