BREAKING CHANGE: This adds a very basic dial queue peer peer. This will prevent multiple, simultaneous dial requests to the same peer from creating multiple connections. The requests will be queued per peer, and will leverage the same connection when possible. The breaking change here is that `.dial`, will no longer return a connection. js-libp2p, circuit relay, and kad-dht, which use `.dial` were not using the returned connection. So while this is a breaking change it should not break the existing libp2p stack. If custom applications are leveraging the returned connection, they will need to convert to only using the connection returned via the callback.
