Add support for Cinder API /v3 endpoint.
A couple of unit tests for /v3 endpoint were added to v3/test_shell.py
to ensure that the v3 shell works, and to also test that modules work
with:
from cinderclient.v2.availability_zones import *
syntax.

Implements: https://blueprints.launchpad.net/python-cinderclient/+spec/add-v3-endpoint-support
This change adds a new admin-api to allow admin to fetch
specified backend capabilities which includes volume stats and
vendor unique properties.
With this command, admin can obtain what the current deployed
backend in Cinder is able to do from the endpoint.
