            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
    1.18 version of the instance (we are currently on 1.21)

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

    (cherry picked from commit 80c109f85a9e8b182e918027731760e91026cb81)
