---------------------------------

I would like to work on this as my first code commit if this is a valid
improvement.
Would this change require a KIP as it touches metrics which are user-facing? Or
do I just need to edit the existing KIP to reflect this change?
> Change Consumer per partition lag metrics to put topic-partition-id in tags
> instead of metric name

> [KIP-92|https://cwiki.apache.org/confluence/display/KAFKA/KIP-92+-+Add+per+partition+lag+metrics+to+KafkaConsumer]
> brought per partition lag metrics to {{KafkaConsumer}}, but these metrics
> put the {{TOPIC-PARTITION_ID}} inside of the metric name itself. These
> metrics should instead utilize the tags and put {{key="topic-partition"}} and
> {{value=TOPIC-PARTITION_ID}}.
> Per-broker (node) and per-topic metrics utilize tags in this way by putting
> {{key="node/topic"}} and {{value=NODE_ID/TOPIC_NAME}}.
