Add interface ExtendedBrokerApi to consume messages with groupId
The intention of this change is to extend the current API allowing
consumers read meesages with the use of a groupId, which enables
multiple consumers to independently read messages from the same source,
facilitating parallelism, fault tolerance, and efficient processing.
It allows for workload distribution and ordered processing within
consumer groups.
