Container workspace to NixOS

[nuest]

NixOS is an interesting Linux distro that is all about declarative configuration and "devops", see e.g. https://www.domenkozar.com/2014/03/11/why-puppet-chef-ansible-arent-good-enough-and-we-can-do-better/

Maybe containerit could create NixOS installation instructions instead of Dockerfiles ?
