Simplify trait bounds on NetworkBehaviour (#1405)

Browse Source 
* Simplify trait bounds requirements

* More work

* Moar

* Finish

* Fix final tests

* More simplification

* Use separate traits for Inbound/Outbound

* Update gossipsub and remove warnings

* Add documentation to swarm

* Remove BoxSubstream

* Fix tests not compiling

* Fix stack overflow

* Address concerns

* For some reason my IDE ignored libp2p-kad
