fix: socket was not connecting + enable reuse address

[anitarua]

Was locally testing v0.10.0 + setting SO_REUSEADDR but it wasn't working.
Used this stackoverflow workaround to set both keepalive and other socket settings instead.

Okay, I think this is what this code should do:

    let stream = TcpStream::connect(&address).await?;
    // For setting socket configuration options available to socket2
    let socket = socket2::SockRef::from(&stream);

    let mut tcp_keepalive = TcpKeepalive::new();
    if let Some(duration) = configuration.tcp_keepalive_duration {
        tcp_keepalive = tcp_keepalive.with_time(duration);
    }

    socket.set_nonblocking(true)?;
    socket.set_tcp_nodelay(true)?;
    socket.set_tcp_keepalive(&tcp_keepalive)?;
    socket.set_reuse_address(true)?;

    let message_reactor: RpcCompletionReactor<

looks great, thank you!
