The following OpenInfra Foundation mailing lists are no longer
required (some were never used at all, some haven't had a post in
many years):
* admin-cert-wg
* ambassadors
* analyst-relations
* app-catalog-admin
* defcore-committee
* foundation-testing-standards
* nov-2013-track-chairs
* openstack-track-chairs
* openstack-travel-committee
* superuser
* tax-affairs
Remove them from our configuration, they'll be manually retired with
the rmlist command once this merges (leaving any public archives
behind for historical reference).
