[PRQ#50042] Deletion Request for python-oslo-messaging

MarsSeed [1] filed a deletion request for python-oslo-messaging [2]: Cleanup of this abandoned, OOD server component package, whose only end-consumers on AUR are defunct, long abandoned Openstack server Python modules (see openstack-nova's deletion request, PRQ#50005, which is representative of the status of the other AUR/openstack-* packages).
