    Implementing this interface allows clients to identify the multi part
    updater, which will process a multi part image and orchestrate the code
    update process. A multi part image is a collection of individual images
    bundled together using a defined encoding format; the multi part updater
    interprets this format to perform code updates across various firmware
    entities. Implementing this interface is optional and required only if the
    client needs to delegate the code update using a multi part image without
    specifying a particular firmware target. Implementations must also provide
    the xyz.openbmc_project.Software.Update interface for the client to transfer
    the multi part image. Only one instance of the MultiPartUpdate exists on the
    BMC.
