  - Merge "Add cloudOwner to VNF adapter call"
  - Add cloudOwner to VNF adapter call

    The BPMN layer has the CloudRegion which includes the CloudOwner
    attribute, but this is not passed to the VNF adapter layer.
    Calls to the Multicloud infrastructure workload need the
    CloudOwner as well.

    This patch adds CloudOwner to the VNF adapter API.  While
    the intended usage is primarily for the multicloud adapter,
    it touches a log of other files - though those do not
    make use of it at this point.
