ok, it appears that in addition to Docker port_mapping, we need to add a
port resource declaration in the task too, with something like:
ports = task.resources.add()
ports.name = "ports"
ports.type = mesos_pb2.Value.RANGES
port_range = ports.ranges.range.add()
port_range.begin=31000
port_range.end=31000
we kinda need to duplicate port declaration (task and docker) in task.
