[MLlib] [SPARK-6713] Iterators in columnSimilarities for flatMap
Use Iterators in columnSimilarities to allow flatMap to spill to disk. This
could happen in a dense and large column - this way Spark can spill the pairs
onto disk instead of building all the pairs before handing them to Spark.
Another PR coming to update documentation.
