Add standalone clickhouse-keeper symlink for independent coordination

Official CH changelog text
Add standalone clickhouse-keeper symlink to the main clickhouse binary. Now it's possible to run coordination without the main clickhouse server. #24059 (alesapin).
Add a standalone clickhouse-keeper symlink to the main clickhouse binary, enabling the coordination service to run independently from the main ClickHouse server.

Why it matters

This feature allows users to run the distributed coordination service separately without requiring the full ClickHouse server to be active. It improves deployment flexibility and resource usage by decoupling ClickHouse Keeper from the database server process.

How to use it

Users can now start the coordination service using the clickhouse-keeper symlink, which points to the main clickhouse binary. Simply invoke clickhouse-keeper directly to run the keeper service standalone.
