Add Nixible

Nix-wrapper for Ansible which handles dependencies etc. and lets you define playbooks in Nix.

I have one major concern with this project, besides this kinda just being a YAML converter and Ansible wrapper:

If I recall correctly, Nix, as a language, does not have ordered lists, such that there are guarantees about list storage or evaluation ordering without using seq or deepSeq. Ansible is very contingent on tasks executing in a specific order (unless you write modules and roles such that the ordering is guaranteed there).

I think this project needs to have guarantees about how the input will line up to the generated YAML to be awesome. Otherwise, the documentation, modularization, and design of the repository itself is quite cool 👀

Thanks for the feedback! But aren't lists in Nix ordered/keep their ordering? Attrsets are impossible to order (they just get ordered alphabetically), but lists always kept their ordering everywhere I used them. The only issue is that it's hard to merge them with the module system, since it cannot know the ordering you intend without any helpers (like mkOrder/mkBefore etc iirc). But I think that's obvious since using lists across multiple files can't have any guaranteed ordering without the user specifying it.

And yeah, the project is nothing special, I'm also fine with closing this since it's like you say mostly just a yaml generator and Ansible wrapper :D
