pre routing handler with body available (or a catch all route)

[dahmadjid]

I am trying to have a single handler that handles all incoming http requests regardless of path or method.
I couldnt find that a catch all route is supported. So i am using the pre_routing_handler. I found that the pre_routing_handler does not have the body available as that is read after the pre_routing_handler is done.

a solution would be:

• adding set_pre_routing_handler_with_body
• or a default_handler that gets routed to in case no other route is matched

I will be happy to do a pull request on either of them as they look straightforward enough to implement.

@dahmadjid could you implement set_pre_routing_handler_with_body and some unit tests? Thanks!
