Create a bootstrap image for Digital Ocean droplets

I need a way to reliably get a NixOS VM provisioned in the cloud, and the
easiest way to do this is to create a qcow2 image, upload it to Digital Ocean,
and use that to start a droplet. This is very much a manual process, but that's
fine, I shouldn't need to do it very often (for now).
