Title:
  python-nova: not region aware when used with quantum

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Hi,

  When used with quantum, python-nova does not pass in any region
  information when constructing a quantum-client, making the compute
  services on my multi-region setup fail when multiple endpoints are
  returned by keystone.

  The problem is that in network/quantumv2/__init__.py,
  _get_auth_token() a quantumclient.client.HTTPClient is created without
  a region_name argument.

  In order to make this work, I had to edit
  nova/network/quantumv2/api.py and add a new parameter to quantum_opts:

      cfg.StrOpt('quantum_region_name',
                 help='region name for connecting to quantum in admin context'),

  and then pass that to the httpclient constructor in
  nova/network/quantumv2/__init__.py with:

              timeout=FLAGS.quantum_url_timeout,
              region_name=FLAGS.quantum_region_name,
              auth_strategy=FLAGS.quantum_auth_strategy)

  and finally set quantum_region_name in nova.conf.

  There may be a more elegant way of achieving all this.
