Subject: Add --os-cloud support

This adds a new option --os-cloud that allows the configuration values
for multiple clouds to be stored in a local file and selected with
a single option.

Internal option names have had 'os_' removed to be comptible with
the options returned from OpenStackConfig().get_one_cloud().

The config file is ~/.config/openstack/clouds.yaml:

Sample
------
clouds:
  devstack:
    auth:
      auth_url: http://192.168.122.10:35357/
      project_name: demo
      username: demo
      password: 0penstack
    region_name: RegionOne
  devstack:
     auth:
       auth_url: http://192.168.122.10:35357/
       project_name: demo
       username: demo
       password: 0penstack
     region_name: RegionOne
