So the v3 API won't exist as a separate major version, but I think its very
important we keep up with the tempest tests so we don't regress. Over time
these v3 api features will either be ported to v2.1microversions (the vast
majority I expect) or dropped. At that point  they'll be "moved" to tempest
testing v2.1microversions.

 But whatever we do we'll need to test against v2 (which we're stuck with
for a very long time) and v2.1microversions (rolling possible backwards
incompatible changes to the v2 api) for quite a while.

I'd really prefer we don't take this route, but its better than nothing.
Incidentally the v3 tempest api tests have in the past found race
conditions which did theoretically occur in the v2 api as well. Just the
different architecture exposed them a bit better.
