Nix(OS) integration

[ShadowJonathan]

An issue documenting potential issues or methods of integrating, packaging, or working with Nix(OS)

Essy assumes a lot of state, I don't know enough about nix to properly handle that state, and to work with other system components (nginx and certbot) to properly do that.

Both nix and guix mostly assume that they have the absolute authority about certbot/nginx. Unless we want to write code to explicitly interact with nix/guix, it will be very difficult.

But, we could probably render a nix/guix template, and calling the system nix/guix to implement that.

I'd say this shouldn't be a focus, maybe a 2.x feature, unless someone experienced with nix/guix contributes it.

V2 is explicitly for extensions and the likes, I'd want to either finish this before that (so 1.x), or leave it dangling for "whenever"
