### Current Behavior

When multi uploading a file for Glacier Instant Retrieval, the operation fails at Complete stage with a message claiming storage class not supported.

### Expected Behavior

It works with real S3.

### How are you starting LocalStack?

With the `localstack` script

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)

localstack start

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

 ```golang
	b, p := parse1(path)
	cmuI := &awsS3.CreateMultipartUploadInput{
		Bucket:       b,
		Key:          p,
		StorageClass: mtypes.StorageClassGlacierIr,
	}
_, err := client.CreateMultipartUpload(context.Background(), cmuI)

```
and process the upload of the part and then complete

### Environment

```markdown
- OS: Ubuntu 20.04
- LocalStack: pro latest
```
