    Change clients_keystone/auth_uri default to public Keystone URL

    By default, the ::heat class configures clients_keystone/auth_uri to the
    value of ::heat::keystone::authtoken::auth_url, which is generally the
    admin endpoint on port 35357.

    However, since this URI can be used by non-admin clients running inside
    instances, such as os-collect-config, a better default value would be to
    use either the public or internal Keystone endpoint, depending on the
    deployment. This commit changes the default to the public Keystone
    endpoint defined in ::heat::keystone::authtoken::www_authenticate_uri.

    It is still possible to provide a custom value using the
    heat_clients_keystone_uri parameter.
