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.

S3 binary cache stores now support configuring the storage class for uploaded objects via the `storage-class` parameter. This allows users to optimize costs by selecting appropriate storage tiers based on access patterns.
|
|
|
|
Example usage:
|
|
|
|
```bash
|
|
# Use Glacier storage for long-term archival
|
|
nix copy --to 's3://my-bucket?storage-class=GLACIER' /nix/store/...
|
|
|
|
# Use Intelligent Tiering for automatic cost optimization
|
|
nix copy --to 's3://my-bucket?storage-class=INTELLIGENT_TIERING' /nix/store/...
|
|
```
|
|
|
|
The storage class applies to both regular uploads and multipart uploads. When not specified, objects use the bucket's default storage class.

See the [S3 storage classes documentation](https://docs.aws.amazon.com/AmazonS3/latest/userguide/storage-class-intro.html) for available storage classes and their characteristics.
