Implement Per-Field-Overriding of Configuration in Augmenter

- Rewrite DeliveryRequestAugmenter to allow per-field-overriding of
  configuration parameters and add test suite.
- Mzs schema change: Move DeliveryRequest/Server into
  DeliveryRequest/Config; Reason: DeliveryRequest/Config contains all
  parameters exclusively needed by moazs to execute the delivery
  request. The msg's server url belongs to this set of parameters.
- WIP: Add prototype implementation of MsgClient and move MsgClient to
  dedicated package.
- Refactor: move TnvzClient to dedicated package.
