[SPARK-21204][SQL][WIP] Add support for Scala Set collection types in serialization ## What changes were proposed in this pull request? Currently we can't produce a `Dataset` containing `Set` in SparkSQL. There's no corresponding internal data type in SparkSQL for a `Set`. A `Set` will be serialized to an array. ## How was this patch tested? Added unit tests.
