JIRA Issue: https://issues.apache.org/jira/browse/SPARK-37285

The following shows the differences with this [PR-10803] :

  1. More accurate algorithm to reduce the variance when the classification data skewed (all 1 or 0 in the bin of a feature) .
  2. Programming based on RDD and better performance.
  3. Separate IV and WOE modules to avoid coupling.
