Set offset commit callback for use with consumer groups.

The results of automatic or manual offset commits will be scheduled for this callback and is served by RdKafka::KafkaConsumer::consume().

If no partitions had valid offsets to commit this callback will be called with err == ERR__NO_OFFSET which is not to be considered an error.

The offsets list contains per-partition information:

• topic The topic committed
• partition The partition committed
• offset: Committed offset (attempted)
• err: Commit error
