Exclude btrfs docker submount from being backed up

See merge request !75

The backup script fails on our Gitlab machine as it tries to remove a
snapshot of the docker submount, which we do not want to backup anyway.

btrfs subvolume snapshot -r /var/lib/docker/btrfs /var/lib/docker/btrfs/backup-snapshot
ERROR: Not a Btrfs subvolume: Invalid argument

It's per worker, and we have 5 of them.

I know this seems a bit weird but this is how the Keycloak templates work. :P

Some tiny markup fixes

Remove arch-boxes stuff (fixes #107)

Closes #107

See merge request !61

This is now built enitrely in GitLab CI in the arch-boxes repo so this is no longer required.

As all these services do maintenance tasks and query the database so
it's better to spread out the load.

Allow the http user to access the conference home directory.
