Allow Configuring S3 Storage Class with s3_storage_class Option

Why it matters

This feature allows users to specify the desired Amazon S3 storage class (e.g., STANDARD, INTELLIGENT_TIERING) for their data stored in S3, enabling cost optimization and better storage management based on access patterns.

How to use it

Set the s3_storage_class option in your ClickHouse configuration file under the corresponding S3 storage section, for example:

<s3_storage_class>STANDARD</s3_storage_class>

This will apply the specified storage class for all data uploads to S3.
