[SPARK-4396] allow lookup by index in Python's Rating
In PySpark, ALS can take an RDD of (user, product, rating) tuples as input.
However, model.predict outputs an RDD of Rating. So on the input side, users
can use r[0], r[1], r[2], while on the output side, users have to use r.user,
r.product, r.rating. We should allow lookup by index in Rating.
