Add upstream patches

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.
