    Class "PortBindingMixin" is removed. Last time this class was used in-tree
    was in Kilo release, in "N1kvNeutronPluginV2" and "SdnvePluginV2" classes.
    No active project is using it anymore.
    Table "portbindingports" is dropped from the database; it was used only in
    "PortBindingMixin".
