Integrate into official agent

[mikker]

Hi! Just stumbled upon this – it's great!

Do you mind if I integrate it or a version of it in the official agent? You're very welcome to submit a PR if you want the contribution credit 😃

Hi, @mikker!
You are too generous, I just modified your original middleware little bit :) But thanks!
I'd love to contribute, give me couple hours.

Nice! I also saw your custom Rails middleware. You use that mainly to have endpoints show up as GET /somewhere? Correct?

[bsedin]

Yep. There are some weird calculations of route pattern to group transactions like GET /posts/:post_id/comments/:id
