This adds in a version-list command that reports the
min/max versions of the Cinder API supported by this
version of the client, and also queries the Cinder API
V3 server to obtain min/max micro-versions and report
those as well.
In addition, we bump the default version of the client to
3.0, of course if you specify V2 in your rc file or on the
cmd line that works fine too.
I did run into one problem where I broke:
cinder.tests.unit.test_shell:test_cinder_service_name
Seems to be some hidden trickery with a fake, fixture or
mock that I can't figure out. For now I added a skip to
that test, but maybe somebody can point out the problem
during review.
