add job to apply tags when based on changes in openstack/releases

Add a new job to run when a patch merges in openstack/releases to apply
the tags described in the patch. For now, only apply those tags to the
openstack/release-test repository so we can test the job. A later patch
will remove that restriction so the job can apply the tags to all
repositories.
