Source complete env in `nix-shell` with `__structuredAttrs = true;` This is needed to push the adoption of structured attrs[1] forward. It's now checked if a `__json` exists in the environment-map of the derivation to be openend in a `nix-shell`. Derivations with structured attributes enabled also make use of a file named `.attrs.json` containing every environment variable represented as JSON which is useful for e.g. `exportReferencesGraph`[2]. To provide an environment similar to the build sandbox, `nix-shell` now adds a `.attrs.json` to `cwd` (which is mostly equal to the one in the build sandbox) and removes it using an exit hook when closing the shell. To avoid leaking internals of the build-process to the `nix-shell`, the entire logic to generate JSON and shell code for structured attrs was moved into the `ParsedDerivation` class.
