Implement OpenStack client clouds.yml configuration file

OpenStack client supports defining one or more sets of credentials
inside a clouds.yml configuration file. A default configuration has
been created named `default` that contains the same admin credentials
from the `openrc` file currently being templated.

The default configuration can be specified using the following:

openstack --os-cloud default <command>
