docs: Signal that this particular entity has been fully processed. The exporter will not send it to this target again
          under this particular export configuration (there is no guarantee another export configuration on the same
          server won't send it, or that it won't be received from another server though, so you must always check whether
          you have an entity and return this status as early as possible if so)
