refactor: nix build set up
The current nix set up was set up to use both nixos installation and nix flake. However, it was set up in a way that is isolated from the active usage and build of bonfire. The following patch changes quite a bit the original nix flake. The purpose is to use the same tooling as that of the current setup for bonfire with just. In doing so, focusing more on development environment for working with bonfire The new set up takes the procedure of using just setup target with WITH_DOCKER=no to imitate a similar local setup. Note: while the nix flake does have sections to create nix packages and even container images to build for bonfire, it is not goal of the current PR to make those sections to work. Ref: #405
