[SPARK-2995][MLLIB] add ALS.setIntermediateDataStorageLevel
As mentioned in SPARK-2465, using `MEMORY_AND_DISK_SER` for user/product
in/out links together with `spark.rdd.compress=true` can help reduce the space
requirement by a lot, at the cost of speed. It might be useful to add this
option so people can run ALS on much bigger datasets.
