[SPARK-12379][ML][MLLIB] Copy GBT implementation to spark.ml
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.
TODO: Ensure performance tests are sufficient to show no regressions.
