[SPARK-13629] [ML] Add binary toggle Param to CountVectorizer
## What changes were proposed in this pull request?
It would be handy to add a binary toggle Param to CountVectorizer, as in
the scikit-learn one:
http://scikit-learn.org/stable/modules/generated/sklearn.feature_extraction.text.CountVectorizer.html
If set, then all non-zero counts will be set to 1.
