    Dear reviewers,
    
    This PR contains handful debug level logs that would make easier to understand how the additional thread is working. To see those log messages, modify `conf/logback.xml` as follows:
    
    ```xml
    <logger name="org.apache.nifi" level="INFO"/>
    <logger name="org.apache.nifi.processors" level="WARN"/>
    <!-- Add this line -->
    <logger name="org.apache.nifi.processors.kafka.pubsub" level="DEBUG" />
    <logger name="org.apache.nifi.processors.standard.LogAttribute" level="INFO"/>
    <logger name="org.apache.nifi.controller.repository.StandardProcessSession" level="WARN" />
    ```
    
    This PR is aimed for ConsumeKafka_0_10. Once this is proved to work properly, I'll create another PR for ConsumeKafka (0.9) similarly.
    
    Thanks a lot in advance!
