add hcloud volume to archlinux.org machine to host ISO files
Due to the massive amount of spam, this MR is already applied.
archlinux.org was low on diskspace and produced a lot of spam/alert mails. Therefore a volume was added to store /srv/ftp
which contains the ISOs and archboot files.
Beforehand the backup was fixed. The state before this change is saved as a snapshot in borg.
