[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
