Since I don't like to update Samba Active Directory Domain Controller
servers in-place (it's never worked as well as you would think it
should), I want the process for replacing them to be as automated as
possible. To that end, I've written `create-dc.sh`, which handles the
whole process of creating and configuring a new ADDC VM. The only
things it doesn't do are transfer the FSMO roles and demote existing DC
servers.
