Released in the wild: ypconfig

Last Friday, I gave a presentation (Dutch) on the `Lekker Weer NLNOG 2017` afternoon. Subject of my presentation was the project I did for ourselves, building our new 10Gbit routers.

Most important task in the project was to be able to reliably configure network interfaces using a `commit && confirm || rollback` method. As far as I could tell, there was no such tool, hence I created it.

Today, we released it into the wild `ypconfig`. We changed the license to BSD-2 to be as permissive as possible but without loosing the credits. Feel free to use, abuse and improve ypconfig!

PS: ypconfig would not be possible without `pyroute2`.
