This has come up a couple of times in IRC now but the people that
probably know the answer aren't available.
There are python-novaclient patches that are adding new CLIs to the v2
(v1_1) and v3 shells, but now that we have the v2.1 API (v2 on v3) why
do we still have a v3 shell in the client? Are there plans to remove that?
I don't really care either way, but need to know for code reviews.
