> keyManagerImpl#listStatus for FSO buckets serves a KeyLocationList but might be large size of response (> 100 MB) and exceed the limit. The problem is KeyLocation field is large enough (> 1MB) so just listing some multi-part uploaded keys exceeds the limit. A possible solution is to reduce KeyLocation size by omitting pipeline fields.

> We checked a List<OzoneFileStatus> in our environment and it turned out that protobufs corresponding to some multi-part keys are larger than 1MB. AFAIK, the maximum IPC length is -100MB- 128MB by default so it easily exceeds the limit.
