fix: VMs can be restarted

Previously, the temporary file for the cloud-init configuration ISO
was left attached to the VM. This meant the VM couldn't be turned off
and back on again: the temporary no longer existed.

Now we detach the ISO file after the VM has booted.

As a side effect, vmadm has gained start and shutdown subcommands, so
that the fix can be tested.
