Handle volume API version enablement

This is a start to have tempest handle Cinder API versions
based on what is actually enabled. There are currently a
lot of places in the code the assume v1 and v2 are available,
but those versions may be disabled, especially as we try to
get everyone moved onto the latest (final?) v3 API version.

There are more areas that should be fixed up before we can
actually just work with v3 only, but this is a start to get
there.
