Add missing labels support for consumer group

[oded-dd]

When running: ./kafka-consumer-groups.sh --bootstrap-server 127.0.0.1:9092 --describe --group my-group-01 I am able to get all the following columns: TOPIC, PARTITION , CURRENT-OFFSET, LOG-END-OFFSET, LAG, CONSUMER-ID, HOST, CLIENT-ID

While kafka_offset_consumer only supports group, partition, topic Need to have support for all of the above as labels
