Review Comment:
`PbSerDeUtils.fromPbWorkerResource` and `PbSerDeUtils.toPbWorkerResource`
already have `networkLocation as a field. We persist it to Ratis in
`AbstractMetaManager.updateRegisterWorkerMeta`. We need the L332-L335 in case
the worker's networkLocation is still set to default rack. In this case, we can
retry to see if it can be resolved.
