Allow Multi-Volume Storage Configuration in Distributed Storage

Allow using multi-volume storage configuration in storage Distributed. #14839 (Pavel Kovalenko).
Allows the Distributed storage engine to utilize multi-volume storage configurations in ClickHouse.

Why it matters

This feature enables the Distributed table engine to leverage multiple storage volumes, improving storage flexibility and management. It solves the limitation where distributed tables could only use a single volume, allowing better resource utilization and performance optimization.

How to use it

Configure the multi-volume storage setup in the server configuration files as usual, then create or alter Distributed tables to use these multi-volume storages. The Distributed engine will automatically support the configured volumes without additional changes to the table definition.
