Jeremy Stanley 0d066f954d Remove unsigned tagging permission from projects
Now that we have a fix in place for Gerrit's tag signature detection
regression, remove the unsafe permission for pushing unsigned tags
to return everything to the state we had prior to the 3.4 upgrade.

# Usage: normalize_acl.py acl.config [transformation [transformation [...]]]
#
# Transformations:
# all Apply all transformations.
# 0 - dry run (default, print to stdout rather than modifying file in place)
# 1 - strip/condense whitespace and sort (implied by any other transformation)
# 2 - get rid of unneeded create on refs/tags
# 3 - remove any project.stat{e,us} = active since it's a default or a typo
# 4 - strip default *.owner = group Administrators permissions
# 5 - sort the exclusiveGroupPermissions group lists
# 6 - replace openstack-ci-admins and openstack-ci-core with infra-core
# 7 - add at least one core team, if no team is defined with special suffixes
# like core, admins, milestone or Users
# 8 - fix All-Projects inheritance shadowed by exclusiveGroupPermissions
