Link stream_handler guide and manual (or any other topic really)

[robertoaloi]

Hooks have been removed in Cowboy 2 as explained here.

Specifically, the documentation states that:

Hooks are gone, their functionality can now be achieved via stream handlers.

But the documentation for stream handlers is a bit limited. It would be convenient to show an example of how a onRequest/onResponse hook would look like in Cowboy 2, when implemented as a stream handler.

Stream handlers are actually documented in a lot more detail in the reference manual.
Probably a good idea to link the two sections.

This is fixed locally but you will need for 2.7 documentation to be uploaded to see it. Closing, thanks!
