IPv6 port binding error with docker composer

[LennardWesterveld]

Hi,

There is a issue by using IPv6 by port/publishing in docker-compose file see for more info also:#2663

How reproduce:

1. Create docker-compose with for example:

version: '2.1'

services:
  web:
    image: 'tutum/hello-world'
    ports:
      - '[2a01:7c8:fffb:31::1]:80:80'

2. docker-compose up
   And you get the follow error:

ERROR: The Compose file './docker-compose.yml' is invalid because:
services.web.ports is invalid: Invalid port "[2a01:7c8:fffb:31::1]:80:80", should be [[remote_ip:]remote_port[-remote_port]:]port[/protocol]

Version information:

docker-compose version 1.9.0, build 2585387
docker-py version: 1.10.6
CPython version: 2.7.9
OpenSSL version: OpenSSL 1.0.1t  3 May 2016
