Add license.
Add a script to stand up a test network.
Hack hack hack
So much hacking. Can push/start/stop jobs now.
Delete the fancy network configuration for home.

Home is just going to be a plain old DHCP machine.
Delete the all the fancy firewall stuff. This is going to be
just a dumb coreos host.
Delete unused "addr" file.
Update to yaml v2.
Add a 'generate' command for testing.
Add a feature to authorized_keys to pull keys from Github.

This mirrors cloud-init's github fetching feature, but the fetching
happens statically when coreadm generates cloud-init, rather than
on boot. This makes the machine more resilient to networking issues
during startup, since the cloud-init file remains entirely static
and local.
