Instruct users to bind http traffic to port 80
Instruct users to bind http traffic to port 80

* If `bind_port` is not defined, it defaults to port `8080`. Thus http
  traffic is served on a non-standard port.
* This causes `http://concourse-url` to not work. Also `http` to `https`
  redirection doesn't work.
* The load balancer is set-up to forward `443` and `80` to the backing web node.
    Also ATC will redirect `80` to `443`. So this should still be nice and secure.
