First pass at functional tests in cinderclient. This patch
just takes some of the basic CLI tests from tempest and moves
them into the cinderclient functional tests.
These are read-only tests, and just do simple field checks
on the tables generated by the basic list commands.
Note: to run use "tox -efunctional", this requires that you
have a full cinderclient env and credentials are set. You may
be either running this locally (say in a devstack env) or
you may have a remote cloud handy that you can just source the
credentials for and run it that way.
