- Update startup banner to print storage class in capitals. This makes it easier to identify different storage classes available. - Update response metadata to not send STANDARD storage class. This is in accordance with AWS S3 behaviour. - Update minio-go library to bring in storage class related changes. This is needed to make transparent translation of storage class headers for Minio S3 Gateway.
