gerrit: vdsm: grant tag permission to stable branch maintainer

Hi, Please grant "Push Annotated Tag" permission to vdsm-stable-maintainers on the stable branches refs/heads/ovirt-* BTW, permissions on refs/heads/ovirt-3.3 refs/heads/ovirt-3.4 and refs/heads/ovirt-3.5 are exactly the same, can we merge them to a single refs/heads/ovirt-* entry? Dan.
