Draft OpenAPI specs v3.0.0 for MetaCPAN API

[jackdeguest]

I have produced for your review this draft MetaCPAN specifications based on the information I could collect from the documentations and the code.
I think this is helpful in providing further clarity on the MetaCPAN API.

I haven't had a chance to look at this yet. We did get the beginnings of swagger docs in https://github.com/metacpan/metacpan-api/pull/862/files

It looks like, for example, there's something here: https://fastapi.metacpan.org/v1/static/v1.yml

Maybe @jberger remembers more about it?

Thanks, @jackdeguest. I apologize for how long this has languished here. How did you aggregate this data?

Very patiently by reading your documentation, reading the code and using your API playground. It took me quite a bit of time.
