Allow App To Choose Between MsgResponse Sinks

- MZS Schema Change: Add "MsgResponseSinks" element to
  mzs:DeliveryRequest/Config that allows sender to configure how
  MsgResponses should be archived.
- ConfigUtil: Interpret MsgResponseSink parameters from Spring
  Environment and merge with ConfigType.
- MsgResponseBackend: Send responses to sinks according to
  MsgResponseSinks in Config
- application.yaml: Add MsgResponseSinks parameter to configuration.
- Uncouple Sink implementations from java.util.function.Function,
  because the sink interfaces are going to differ and there is no need
  to unite them under one interface.
- Add and test LogResponseSink, which logs responses to it's logger.
- MsgResponse: Add JAXB getter for response. Reason: Can be passed to
  marshaller.
