Add nfsboot configuration extension
This configuration-extension removes every network interface but the
loopback interface from /etc/network/interfaces and stops /etc/fstab
from mounting "/".
It will only do this if the environment variable NFSBOOT_CONFIGURE is
set on the `morph deploy` command-line.
