  - Add upstream patches

    When we building kolla images in OPNFV jenkins job, we need to
    clone code directly from openstack/kolla project and patch it
    with necessary patches needed by OPNFV.

    This is the first patch focus on ODL and DPDK integration. To
    use it, please clone openstack/kolla's stable/pike branch first
    then apply patch by using git apply command.

    This PS also solved git clone risk found by Anteater by
    deleting url variable in git clone command.
