Hi! I have a small contribution I was hoping that you would consider.
The feature is in the StatisticsBroker(Plugin), where I have added an optional request property, which if present will on the reply message include the "BrokerInTime" for the first message in the destination, as a field "firstMessageTimestamp". How do you want me to do such a suggestion? Should I first open an issue / feature request, and then do a PR for it, or just submit a PR directly? Kind regards, Endre Stølsvik
