Add func test for compute 2.94

The only thing that changes in 2.94 is server-side validation of the
``hostname`` parameter, so no client-side changes are needed other
than to bump novaclient's max supported microversion (see dependent
patch), but it's still nice to have a test to assert that osc pipes
through the correct value to the Nova API.
