So I'm inclined to say go with #1 in this case. If you're not doing volume
attach then there is no reason to run cinder in the gate with tempest. We get
the cinder API test coverage on every other job and it's not like work on ironic
where it doesn't touch cinder is going to break things. I really don't see a
case where having both cinder and nova enabled but no volume attach is useful
with tempest, because that's basically the integration point between the 2
projects.

The only downside to doing number 1 is that there will be a chicken and egg
problem when you go to finish the ironic cinder support. But, that's easily
solved with a throwaway patch which will run with the ironic cinder support
patch and the tests with cinder enabled.
