Well, this isn't a tempest test or anything we can just skip. This is
part of grenade's workflow to do upgrades. It goes:

* run smoke tests on $old
* create some resources to persist across upgrades (this ensures we
  don't break existing resources when upgrading)
* upgrade to $new
* run more tempest tests

We can't just skip the resource create phase here.
