------------------------------------------------------------------
This will happen for all of the configs that are read directly from Properties
in KafkaConsumer i.e :
* _link.poll-timeout_
* _flink__.disable-metrics_
* _flink.partition-discovery.interval-millis_
They are logged as unknown, but they are used, so it's just misinformation
problem. I can fix that :)
