Accessing request.form in a @app.listen("request") raises a LazyBody error.

I don't really know if it is a bug or a feature.

I was logging the request parameters using a @app.listen(request) decorator but at this point the request.body is not loaded yet.
I changed it for @app.listen("response")

I'd say it's a bug.

Semantically, the signal request should provide a full usable request. But we need a way to intercept the request without loading the body, and the plan is to add a headers signal that is sent once headers are fully parsed (so one can check auth and such at this moment, without dealing with the body).

Here is the original PR, and what we should implement back I think: https://github.com/pyrates/roll/pull/77/files#diff-2b45f513911dff50c92a6d00c244b62aR62-R70

cc @davidbgk I'll try to have a look but I'm not sure I'll have time this week so if you have a slot, go for it :)

Thanks for the report @Natim :)
