Request: Syntax highlights for http

[damccull]

I know syntax highlighting engine is being considered for a replacement and tracked in #2758.

Whenever there's time, I would like to see a syntax for raw HTTP request syntax like:

POST /users/123/profile?thing=yes&blarg=no HTTP/1.1
Host: api.example.com
Content-Type: application/json
Authorization: Bearer your_access_token

{
  "firstName": "John",
  "lastName": "Doe",
  "bio": "A short bio about myself."
}

I use these on some of my documentation and it would be really nice to have the parts highlighted. Currently I codefence them with the 'http' language, but since there's no syntax for it, they just end up plain.

I can wait for the new engine, but please consider adding this syntax eventually.

Edit: Ooh, github does it nicely...let's get this in zola too!
