Volume API v2 has been deprecated for a long time. There is no reason to use volume v2 in clouds.yaml by default. This commit also drops "--os-identity-api-version 3" from write_clouds_yaml in functions -common as "3" is the default value of tools/update_clouds_yaml.py. They are hardcoded in DevStack so there is no reason to pass it. Change-Id: Ie84026a3d19f7711fc781b7012355096c7ff6b5a
