The iotronic repos haven't seen any activity for at least 5 years, so they can be considered inactive. The are using outdated openstack jobs or templates and are this blocking cleanups [0]. Therefore we a dropping these repos from Zuul, but do leave the gerrit setup in place, so action can easily recover should interest in these repos return. Also drop the empty IRC channel #openstack-iotronic from our configuration.
