> If an S3 multipart upload is created but no part is upload the part list can't be called
because it throws HTTP 500:
> Create an MPU:
> {code}
> aws s3api --endpoint http://localhost:9999 create-multipart-upload --bucket=docker --key=testkeu
                                        
> {
>     "Bucket": "docker",
>     "Key": "testkeu",
>     "UploadId": "85343e71-4c16-4a75-bb55-01f56a9339b2-102592678478217234"
> }
> {code}
> List the parts:
> {code}
> aws s3api --endpoint http://localhost:9999 list-parts  --bucket=docker --key=testkeu
--upload-id=85343e71-4c16-4a75-bb55-01f56a9339b2-102592678478217234
> {code}
> It throws an exception on the server side, because in the KeyManagerImpl.listParts the
 ReplicationType is retrieved from the first part:
> {code}
>         HddsProtos.ReplicationType replicationType =
>             partKeyInfoMap.firstEntry().getValue().getPartKeyInfo().getType();
> {code}
> Which is not yet available in this use case.
