    neutron: only get port id when listing ports in validate_networks

    The validate_networks method is called from the compute API before
    casting off to build instances. If the project has a lot of ports, the
    list call to neutron can be slow, so we should optimize this method as
    much as possible. One way to do that is rather than get the port details
    back, we just get the id since all we care about is the number of ports
    assigned to the project.
