One folder for everything means moving 4 or 5 modules only, so I think that
be a good option.
I would prefer to avoid though having a lot of v3 test classes that inherit
v2 test classes, and just set _api_version = 3.
As long as we can assume we will never run v2 and v3 in the same job, we
have cinder_api_version as a configuration setting, to determine which
endpoint to hit when running the volume tests.

Apart from the volume tests, if we split the gate jobs into standard one
plus and extra v2 one, we should make sure that all tests that use the
use a consistent version of the volume API. Nova as well should be
possible to use the same volume API version.
