linked cache.nixos.org diagnostics script outdated

[thoughtpolice]

I'm working on something like this but the thing is, it's unclear what kind of diagnostics the previous script was really intending to provide, outside of just running extremely obvious checks like "is your router turned on". Which is fine, of course, sometimes the router's turned off!

We can do some better stuff, potentially, if we bake some extra logic into the CDN layer to give feedback. (For instance, an obvious one is "What Fastly datacenter is the user connecting to", which is potentially extremely relevant.) This has been part of my long-term goals with the new binary cache setup, but very low in priority vs having everything else work well.

I also think it would be nice if the script was actually nix run-able. For instance you could stuff a default.nix into the included gist that just used <nixpkgs> for dependencies (so you don't have to contact the cache anyway) to run everything for you.

Happy to hear any suggestions from Graham if he has them.

The index.html can now be changed with terraform over here: https://github.com/NixOS/nixos-org-configurations/blob/7d5ff0a5526edeedcf22a39f50fd72e12a137f65/terraform/cache/index.html#L47-L49

All we need now is an updated diagnostic script.

I did a quick pass in 93f42d6. Feel free to propose further improvements!
