[SPARK-8484] [ML]. Added TrainValidationSplit for hyper-parameter tuning.
- [X] Added TrainValidationSplit for hyper-parameter tuning. It randomly
splits the input dataset into train and validation and use evaluation metric on
the validation set to select the best model. It should be similar to
CrossValidator, but simpler and less expensive.
- [X] Simplified replacement of https://github.com/apache/spark/pull/6996
