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
