openstack-origin-git currently only supports YAML that specifies the git repositories to deploy from. This adds support for default openstack-origin-git values. The default values supported are: icehouse, kilo, liberty, mitaka, and master. For example: openstack-origin-git=master Change-Id: I094695a343cd3d1e07b516a0c3cdc401437c6c34
