In keeping with its name change to the Open Infrastructure
Foundation, the confidential board mailing list is moving from
lists.openstack.org to lists.openinfra.dev. Set up address
forwarding and Web redirects to reflect this, and add a mailman list
entry for it (there's no old one to remove as it wasn't previously
included in our configuration).
Note that this should be a no-op when it merges, as the list move
will be handled manually while deployment is temporarily disabled
for the server.
