> RobustScaler is a kind of widely-used scaler, which use median/IQR to replace
> mean/std in StandardScaler. It can produce stable result that are much more
> robust to outliers. It is already a part of
> [Scikit-Learn|https://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.RobustScaler.html#sklearn.preprocessing.RobustScaler].
> So far, it is now implemented in ML.
> I encounter a practical case that need this feature, and notice that other
> users also wanted this function in SPARK-17934, so I am to add it in ML.
