    @ckadner -- I wiil test the anntinutj PR in the next days, but I need to 
repalce this in my current setup. I'm just using my own modified version of the 
MQTT-connector that does quite the same of anntinutj but, however, it doesn't 
support multi-topic input and so it wastes resources allocating multiple MQTT 
receivers, one for each supplementary topic that has a different pattern (i.e. 
cannot be inserted with wildcards).
    
    The anntinutj PR is very important because:
    
    - preserves resources in the Spark clusters
    - gives the opportunity to filter topics, an thus to efficiently manage 
payloads, inside the Spark programs.



> New API for subscribing from a list of MQTT topics and Return tuple of

> I am working in IoT Project. As part of MQTT-Kafka bridge program development 
> I used Bahir. I feel that it will be a good feature to prove a new API to 
> support a list of MQTT topic as input and output as a tuple of <Topic, 
> Message>. This will be useful to reduce resource usage in case of multiple 
> topic subscription. I had developed this feature a like to integrate
