Added support for prefix-based configuration of S3 endpoints in ClickHouse.
Why it matters
This feature allows users to specify S3 endpoint settings using prefixes, enabling more flexible and granular configuration for different S3-compatible storage services or environments. It solves the problem of applying uniform S3 settings by allowing specific endpoint configurations based on prefixes, improving customization and compatibility.How to use it
Users can configure S3 endpoints by defining settings with specific prefixes corresponding to different S3 targets within their ClickHouse configuration files, enabling tailored S3 endpoint behavior depending on the use case.
