Subject: [PATCH] newvm: Add domain argument

Now that we have multiple domains (_pyrocufflink.blue_ for AD domain
members and _pyrocufflink.black_ for the new machines), we need a way to
specify the domain for new machines when they are created.  Thus, the
`newvm.sh` script accepts either an FQDN or a `--domain` argument.  The
DHCP server will register the DNS name in the zone containing the
machine's domain name.
