>             Project: Spark
>          Issue Type: Sub-task

> Currently, GBTs in spark.ml wrap the implementation in spark.mllib. This is preventing
several improvements to GBTs in spark.ml, so we need to move the implementation to ml and
use spark.ml decision trees in the implementation. At first, we should make minimal changes
to the implementation.
> Performance testing should be done to ensure there were no regressions.
