    Update devref to catchup with libnetwork 0.5.0

    Updating devref to address following changes:
    1. Removal of 'service' from docker
    2. Vendoring in IPAM driver support from libnetwork to docker. This
    allows user to pass subnet of their choice using docker cli. In case
    if user does not provide subnet related configuration and neither
    remote ipam driver while creating network, built-in ipam driver will
    provide default subnet configuration.

    refer to the links for details:
