KIP-1267 — KIP-1267: Tiered Storage Cost Attribution Metrics

Discussion Tiered StorageMetrics

Adds per-topic and per-consumer-group tiered storage cost attribution metrics (remote bytes fetched, remote API call counts) to enable operators to charge back object storage costs to individual tenants. With tiered storage, remote fetch operations (S3 GetObject calls) incur variable per-request costs, but Kafka currently exposes no metrics to attribute those costs to specific topics or consumer groups.
