Review comment:
@singer-bin
- As well as other reconfiguring properties of DataNode, I prefer to be able
to update parameters by calling `reconf.. .Parameters(property, newVal)`.
- I think this PR is similar to #3863. Instead of creating the new method of
`reconfSpaceUsedKlass()`, how about extending `reconfDfsUsageParameters` to
update `fs.getspaceused.classname`?
