Add libp2p-request-response protocol. (#1596)
* Add the libp2p-request-response protocol.

This crate provides a generic implementation for request/response
protocols, whereby each request is sent on a new substream.

* Fix OneShotHandler usage in floodsub.

* Custom ProtocolsHandler and multiple protocols.

  1. Implement a custom ProtocolsHandler instead of using
     the OneShotHandler for better control and error handling.
     In particular, all request/response sending/receiving is
     kept in the substreams upgrades and thus the background
     task of a connection.
  2. Support multiple protocols (usually protocol versions)
     with a single `RequestResponse` instance, with
     configurable inbound/outbound support.

* Small doc clarification.

* Remove unnecessary Sync bounds.

* Remove redundant Clone constraint.

* Update protocols/request-response/Cargo.toml

Co-authored-by: Toralf Wittner <tw@dtex.org>

* Update dev-dependencies.

* Update Cargo.tomls.

* Add changelog.

* Remove Sync bound from RequestResponseCodec::Protocol.

Apparently the compiler just needs some help with the scope
of borrows, which is unfortunate.

* Try async-trait.

* Allow checking whether a ResponseChannel is still open.

Also expand the commentary on `send_response` to indicate that
responses may be discard if they come in too late.

* Add `RequestResponse::is_pending`.

As an analogue of `ResponseChannel::is_open` for outbound requests.

* Revert now unnecessary changes to the OneShotHandler.

Since `libp2p-request-response` is no longer using it.

* Update CHANGELOG for libp2p-swarm.
