feat(libstore): add S3 storage class support

Browse source 
Add support for configuring S3 storage class via the storage-class
parameter for S3BinaryCacheStore. This allows users to optimize costs
by selecting appropriate storage tiers (STANDARD, GLACIER,
INTELLIGENT_TIERING, etc.) based on access patterns.

The storage class is applied via the x-amz-storage-class header for
both regular PUT uploads and multipart upload initiation.
