Add a cage module to nixos. This can be used to make kiosk-style systems that boot directly to a single application. The user (demo by default) is automatically logged in by this service and the program (xterm by default) is automatically started. This is useful for some embedded, single-user systems where we want automatic booting. To keep the system secure, the user should have limited privileges. Based on the service provided in the Cage wiki here: https://github.com/Hjdskes/cage/wiki/Starting-Cage-on-boot-with-systemd Co-Authored-By: Florian Klink <flokli@flokli.de>
