> {{DataNode#refreshVolumes}} passes the list of NamespaceInfos to each dataset when adding new volumes.
> This list should be filtered by the correct NodeType(s) for each dataset. e.g. in a shared HDFS+Ozone cluster, FsDatasets would be notified of NN block pools and Ozone datasets would be notified of Ozone block pool(s).
