Add ServiceURL configuration for S3-compatible APIs

- Introduced a new property `ServiceURL` in `AwsBlobProviderConfiguration` to allow custom service URLs for S3-compatible APIs like MinIO and DigitalOcean Spaces.
- Updated `AwsBlobProviderConfigurationNames` to include the new `ServiceURL` constant.
- Modified `DefaultAmazonS3ClientFactory` to utilize the `ServiceURL` when creating the S3 client configuration, enabling support for custom endpoints.
