new: Module to install FreeBSD 10.0. It uses the same aproach that is
used with Windows installation, where the iso is modified to
incorporate a rules file. Bsdinstall reads such a file (from /etc/) and
install the new system according to the rules and scripts found inside.
After installing the base groups it's possible to install additional
packages specified in the tdl. Running extra commands is not yet
possible.

Now all FreeBSD needs is cloud-init so the resulting image can be
deployed and used in the cloud.
