A system table for monitoring Kafka consumers

A system table to monitor Kafka consumers. #50999 (Ilya Golshtein).
Introduces a system table in ClickHouse to monitor Kafka consumers.

Why it matters

This feature provides visibility into Kafka consumers within ClickHouse, allowing users to monitor consumer status, progress, and metrics directly through a system table. It helps in troubleshooting, performance tuning, and ensuring reliable data ingestion from Kafka.

How to use it

Users can query the new system table designed for Kafka consumer monitoring using standard SQL SELECT statements. No additional configuration is required beyond having Kafka tables set up; simply query the system table to access consumer metrics and status.
