Integrate Sign.Verification and Improve Error Handling of Pipeline

- Ensure proper communication of errors between pipeline and mzs
  service by converting MoaZSExceptions into DeliveryRequestStatus
  messages.
- Revise MoaZSException: Add optional fields; those fields are a)
  helpful to construct meaningful error messages and b) optional
  because, depending on where an exception appears, either existent or
  non-existent and thus optional. Add inner-class Builder.
- Integrate Signature Verification into pipeline and add Stub for
  SignatureVerification.
- Move TNVZResponse's Mimetype check into dedicated class (Reason:
  separate abstration layers).
- Update api changes in testcases.
