Display CPU and Memory Metrics in ClickHouse Local

Why it matters

This feature provides users with real-time visibility of system resource usage (CPU and memory) when working in clickhouse-local. It helps in monitoring and diagnosing resource-related issues without leaving the ClickHouse environment.

How to use it
