            Add numa_node to PCIDevice

            The change extends the PCI device model and its DB representation.
            Query libvirt for the PCI devices numa node.

    This patch adds the necessary changes to master. We only bump the
    PciDeviceList version, and add a backporting rule to obj_relationship
    dictionary of the Instance object, to start sending the new version with
    1.20 version of the instance (we are currently on 1.21).

    Landing this patch fixes versioning going forward, and all interactions
    that request the PciDeviceList through the Instance object, however
    applying the stable/kilo backport of this is required for Kilo nodes to
    start requesting the latest version of PciDevice through PciDeviceList.

    We can't send 1.2 PciDeviceList to Kilo nodes yet because of
    related-bug 1475254 , so we have to backport this to Kilo first before
    we can start sending the 1.2 to Kilo nodes.
