Change msg service: Acknowledge Response iff Backend Succeeds
- Before: Upon receipt of a message via the msg/ endpoint, MOA ZS would immediately acknowledge the receipt without verifying that the message was successfully processed by the backend. - Now: MOA ZS receives a message via the msg/ endpoint, forwards it to the sinks, and acknowledges the receipt if and only if the processing succeeded.
