--------------------------------------------------------------------
Attaching the updated patch with new test.
bq. Nitpick - convert(DatanodeInfoProto di) can use the new DataNodeInfo
constructor
This constructor was used intentionally as new constructor was expecting all
fields to be specified, instead of just DatanodeID
Please review.

> HDFS-5215 changed the DataNode volume available space calculation to consider
> the reserved space held by the {{dfs.datanode.du.reserved}} configuration
> property. As a side effect, reserved space is now counted towards non-DFS
> used. I don't believe it was intentional to change the definition of non-DFS
> used. This issue proposes restoring the prior behavior: do not count
> reserved space towards non-DFS used.
