[PATCH cluster v4 1/2] cluster files: add used_vmids.list

[Severen Redwood]

Add `/etc/pve/used_vmids.list` to the list of cluster files, which will
be used for recording previously used VM/CT IDs. This is required so
that we can optionally ensure that such IDs are not suggested by the
`/cluster/nextid` API endpoint.
