Move DDC `adminws` to a VM
We need to free up the box currently used for the
adminws so that we can redeploy the box as a storage server (see #169 (closed)).
A couple of qutestions: should it remain on the Apt-side or move to the CloudLab-side or does it matter? Probably it will be a VM on one or the other control nodes. How much RAM does it need? Ideally we want to use this node to provide access to power data archival space (see #295 (closed)), so we either need a big virtual disk or plumb through access to a blockstore.
