SPARK-1467: Make StorageLevel.apply() factory methods Developer APIs
We may want to evolve these in the future to add things like SSDs, so let's mark them as experimental for now. Long-term the right solution might be some kind of builder. The stable API should be the existing StorageLevel constants.
