# run_instance only sends a request_spec, and an instance may or may
# not have been created in the API (or scheduler) already. If it was
# created, there's a 'uuid' set in the instance_properties of the
# request_spec.
# (littleidea): I refactored this a bit, and I agree
# it should be easier :)
# The refactoring could go further but trying to minimize changes
# for essex timeframe
