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:
