Hack to read exposed ports from container options in deimos

docker.py

inner = inner_ports(image)
if inner == []:
    log.info("no port exposed in image, looking for --expose")
    for i, opt in enumerate(options):
        if opt == "--expose":
            log.info("found " + opt)
            inner = [int(options[i+1])]
            break
port_pairings = list(itertools.izip_longest(ports, inner))

Replace line 21 in deimos/docker.py with this.
