Describe the bug

When publishing as prometheus metrics the kafka gauge and counter metrics are exported as

# TYPE messaging_kafka_consumer_queue_message_count_Number of ops (callbacks, events, etc) waiting in queue for application to serve with rd_kafka_poll() gauge
# UNIT messaging_kafka_consumer_queue_message_count_Number of ops (callbacks, events, etc) waiting in queue for application to serve with rd_kafka_poll() Number of ops (callbacks, events, etc) waiting in queue for application to serve with rd_kafka_poll()
messaging_kafka_consumer_queue_message_count_Number of ops (callbacks, events, etc) waiting in queue for application to serve with rd_kafka_poll()

These cannot be scraped by prometheus
