Subject: [PATCH] Add hub for MOEM-IGE group

- traefik tag bump was required to get LE working. It's
  already bumped in newer z2jh versions
- NFS server was again set up manually, and needed the `insecure`
  flag - even though other hubs are setup the same way and didn't
  need this. NFS situation needs to be sorted.
