Revert "[jabley] Apparently Vagrant DNS is better now"

This reverts commit 01b4de3a621623f09f5d7aa6599f0814538b3449.

Vagrant DNS does not appear to play nicely with multiple VMs. When I try
to spin up pp-puppet, it causes puppet/development VM to crash and vice
versa. I think this is the only thing I've changed recently?
