Refactor MsgResponse and its IDs

StoreSOAPBodyBinaryInRepositoryInterceptor:
- Replace "generate body's id via concatenation" with "give the right
  generator function the app delivery id and let the generator
  function do the work". Reason: Prevent the logistics of deriving IDs
  to spill into unrelated components.

MsgResponse refactor:
- Make MsgResponse an abstract class.
- Derive ResponseID's  ONLY in MsgResponse::createResponseID.

Others:
- Ensure that all invocations to DeliveryRepository.getResponse and
  BinaryRepository.get use "responseID" instead of ambiguous "id" or
  incorrect "appDeliveryID".
- Move SingleThreadedDeliveryPipeline into process package.
