* Nodes are marked offline, then deleted; given enough time. Nodes can come back for various reasions (i.e. netsplit). When they come back, have them recreate the node Instance if AWX_AUTO_DEPROVISION_INSTANCES is True. Otherwise, do nothing. The do nothing case will show up in the logs as celery job tracebacks as they fail to be self aware.
