Ian Wienand 270daa1b1a Serve meetings.opendev.org
This site replaces eavesdrop.openstack.org.  I think this name makes
more sense.

That is/was being published by jobs directly pushing this onto the
eavesdrop server.  Instead, the publishing jobs for irc-meetings now
publish to /afs/openstack.org/project/meetings.opendev.org.  This
makes the site available via the static server.

This is actually a production no-op; nothing has changed for the
current publishing.  It is still todo to figure out the correct
redirects to keep things working from the existing
eavesdrop.openstack.org and stop the old publishing method.

Depends-On: https://review.opendev.org/c/opendev/zone-opendev.org/+/794085
