Support resolving hostnames Until now the crate supported only IP addresses and systemd sockets. This was troublesome because it prevented the popular `localhost:1234` format. This commit changes the behavior so that if parsing of `std::net::SocketAddr` fails it attempts to parse it as `hostname:port`. `bind_*()` methods were also modified to be async because of this.
