Tim Kuehn 8dc3711a80 Use async fn in generated traits!!
The major breaking change is that Channel::execute no longer internally
spawns RPC handlers, because it is no longer possible to place a Send
bound on the return type of Serve::serve. Instead, Channel::execute
returns a stream of RPC handler futures.

Service authors can reproduce the old behavior by spawning each response
handler (the compiler knows whether or not the futures can be spawned;
it's just that the bounds can't be expressed generically):

    channel.execute(server.serve())
           .for_each(|rpc| { tokio::spawn(rpc); })
