[SPARK-9493] [ML] add featureIndex to handle vector features in
IsotonicRegression
This PR contains the following changes:
* add `featureIndex` to handle vector features (in order to chain isotonic
regression easily with output from logistic regression
* make getter/setter names consistent with params
* remove inheritance from Regressor because it is tricky to handle both
`DoubleType` and `VectorType`
