Add the ability to load custom dashboards for system.dashboards from configuration files, overriding the default preset dashboards.

Why it matters

This feature enables users to define and customize their own dashboards via configuration, allowing tailored monitoring and visualization that better fits their specific needs instead of relying on the built-in default dashboards.

How to use it

Users can create or modify dashboard configuration files to define their custom dashboards. Once the configuration is set and loaded by ClickHouse, these dashboards will replace the default dashboards shown in system.dashboards.
