The legacy redirects that are on old-wiki.o.o should go away. But they
certainly should stop being served by old-wiki.
Note, this excludes quantum, which is a dead redirect anyway and
workitems which never really got off the ground and only contains out of
date info from diablo-4.

This provides a hollow "devstack.org" vhost as a permanent redirect
to the docs.openstack.org/developer/devstack site. It also aliases
*.devstack.org to the same vhost.
