[FLINK-2102] [ml] Add predict operation for LabeledVector
Add predict function for labeled data for SVM and MLR.
These functions return for each example in the input DataSet[LabeledVector]
a pair (Double, Double) - (truth, prediction)
This output can then be used to evaluate the performance of the Predictors

> Project: Flink
> Issue Type: Improvement
> Components: Machine Learning Library
> Reporter: Theodore Vasiloudis
> Assignee: Theodore Vasiloudis
> Priority: Minor
> Labels: ML
> Fix For: 0.9
>
>
> Currently we can only call predict on DataSet[V <: Vector].
> A lot of times though we have a DataSet[LabeledVector] that we split into a
> train and test set.
> We should be able to make predictions on the test DataSet[LabeledVector]
> without having to transform it into a DataSet[Vector]
