Looks reasonable. I'm not keen on the name prometheus-app-pure though (especially as it has the side-effect of registering collectors!). Maybe prometheus-reporter?

It might make more sense to keep the cmdliner stuff for cohttp in app. That would also avoid exposing the type (which is likely to change - see #51).

We should also be able to include it in the mli, to avoid duplication.

This is a pretty early PR that just moves the code around a bit to not depend on cohttp.
Tests seems to pass on my machine at least.
