Subject: [PATCH] Fix #1174: remove pve-qm-drive

Let 'cdrom' use the pve-qm-ide format, as it's supposed to
be an alias to ide2.
We're not using the 'alias' schema property since the qemu
configs still use a custom parser (due to the
pending-changes system and the filename-to-volume-id
conversion for legacy support) which does not deal with
schema aliases.
