[SPARK-13097][ML] Binarizer allowing Double AND Vector input types

This enhancement extends the existing SparkML Binarizer [SPARK-5891] to allow Vector in addition to the existing Double input column type.

A use case for this enhancement is for when a user wants to Binarize many similar feature columns at once using the same threshold value (for example a binary threshold applied to many pixels in an image).

This contribution is my original work and I license the work to the project under the project's open source license.
