Support using the Keystone V3 API from the Nova CLI

This changeset enables support for Keystone V3 authentication
on the Nova CLI. This provides consistency between using
novaclient as the Nova CLI and using it as a library
as the Keystone V3 support already exists for the libary usecase.

The bulk of the change surrounds the use of the keystoneclient
session object for authentication, retriving the service catalog,
and HTTP connection/session management.
