treewide: replace attrs by formats or types.anything

[berbiche]

Description

Replaces all instances of:

• types.attrs with types.attrsOf types.anything where it made sense
• types.attrs with pkgs.format.{json,yaml,ini} where it made sense

There are places where replacing types.attrs broke the evaluation and so wasn't done:

• pam
• home-environment
• bash
• zsh

Checklist

• Change is backwards compatible.

• [x ] Code formatted with ./format.

• Code tested through nix-shell --pure tests -A run.all.

• Test cases updated/added. See example.

• Commit messages are formatted like

  {component}: {description}
  
  {long description}
  

  See CONTRIBUTING for more information and recent commit messages for examples.

• If this PR adds a new module

  • Added myself as module maintainer. See example.

  • Added myself and the module files to .github/CODEOWNERS.

The build will fail because this hasn't been rebased on top of #1594

[berbiche]

The tests case run much slower now (they use much much more memory). I'll have to investigate.

This has nothing to do with these changes.

@rycee it would be great if this could move forward as types.attrs is very annoying to deal with.

Thanks! Looks good I think, I just got confused about the commented line.

[berbiche]

@rycee I just now remembered reading about a module that gave importance to the ordering of keys in its JSON configuration.
Do you happen to know what module that was?
The formatting with jq actually reorders keys based on alphabetical ordering.

[rycee]

@berbiche I can't recall which one that might be but I don't think it is any of these since they all use types.attrs or types.attrsOf, which orders the keys.

Thanks! Merged to master, now that its clear that the test performance issue is unrelated.
