> [HDFS-4015] counts and reports orphaned blocks  {{numberOfBytesInFutureBlocks}} in safe
mode. It was implemented in {{BlockManager}}. Per discussion in [HDFS-9129] which introduces
the {{BlockManagerSafeMode}}, we can move code that maintaining orphaned blocks to this class.
> Leaving safe mode checks blocks with future GS in {{FSNamesystem}}. This code can also
be moved to {{BlockManagerSafeMode}}.
