The OpenInfra Summit organizers have decided they're going back to
using the term "track chairs" instead of "programming committee" and
would like to switch to a new mailing list name in order to
coordinate things for the upcoming conference. Remove the old list
from our configuration when adding the new one, and set up a
forwarding alias for the old list's address so that replies to
previous messages will end up in the right place.
