CoreOS dev container

Pending real documentation.... We do have a development container which includes the same toolchain version that was used to build CoreOS but it works under systemd-nspawn, not docker, and isn't documented. But here is a quick guide that may be a useful starting place.

# on coreos
bunzip2 coreos_developer_container.bin.bz2
sudo systemd-nspawn -i coreos_developer_container.bin --share-system
# And now we cry because --network-interface on systemd-nspawn is broken. :(
