Implement Pipeline Flow and mzs2msg Conversion

- Implement and test conversion from mzs:DeliveryRequest to
  msg:DeliveryRequest with the "convert-pojos-by-hand"-strategy.
  Reason: The chosen strategy benefits from JAXB's strong typing,
  which is useful in this scenario: Differences between msg and mzs
  are nuanced and easy to overlook. The chosen strategy is,
  unfortunately, verbose and could become expensive to maintain.
- Update SameThreadDeliveryPipeline: Integrate tnvz query, conversion,
  and msg query.
- Add MsgClient stub.

tnvz:
- Change TnvzClient stub interface.
- Implement mimetype mismatch check from tnvz Response.
- Put p:Identification from tnvz response into msg:DeliveryRequest.

MZS Schema changes:
- Replace DeliveryRequest/Sender/Person with CorporateBody (because
  thats the only sender that is allowed by zusemsg) and add a
  SenderProfile choice.
- Add ID Attribute to DeliveryRequest/Sender because
  msg/DeliveryRequest/Sender/AbstractSenderPersonType also has an id
  attribute.
- Remove PersonDataType because it's dead code.
