      Description

      This is first reported by Jeff Klukas.

      Similarly as we handle null keys in KStream join and aggregations in KAFKA-3561 (https://github.com/apache/kafka/pull/1472), for KTable.groupBy operators we should also gracefully handle null keys by filter them out since they will not be participating in the aggregation.
