Shutdown S3(Azure/etc)Queue streaming before shutting down any

Shutdown S3(Azure/etc)Queue streaming before shutting down any tables on server shutdown. #83530 (Kseniia Sumarokova).
Shutdown S3/Azure queue streaming cleanly before shutting down tables during server shutdown.

Why it matters

To ensure that streaming from external storage queues such as S3 and Azure Blob Storage is terminated properly before tables are shut down on server shutdown. This prevents potential data loss or corruption by allowing the streaming processes to finish gracefully.

How to use it

This feature is applied automatically during the ClickHouse server shutdown process and requires no manual intervention from users.
