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.
