KAFKA-3233: expose consumer per-topic metrics In version of 0.8.2.1, the old consumer will provide the metrics reporter per-topic consumer metrics under group 'ConsumerTopicMetrics'. For example: *.ConsumerTopicMetrics.clientId.[topic name].BytesPerSec.count *.ConsumerTopicMetrics.clientId.[topic name].MessagesPerSec.count These consumer metrics are useful since it helps us monitor consumer rate for each topic. But the new consumer(0.9.0.0) doesn't expose per topic metrics anymore, even though I did find sensor objects in consumer metrics object collecting per-topic metrics. After investigation, I found that these sensors are not registering any KafkaMetrics.
