Drop rsync.pl config from salt for osd and o3
oops, found that we have the repo still installed and configured for both osd and o3 which we should remove before we can call this done. E.g. see https://gitlab.suse.de/openqa/salt-states-openqa/-/blob/master/openqa/server.sls#L177 . IMHO as long as we have the repo checked out and covered in salt we are not done with the cleanup.
