Josh Rosen c9fa870a6d [SPARK-7687] [SQL] DataFrame.describe() should cast all aggregates to String
In `DataFrame.describe()`, the `count` aggregate produces an integer, the `avg` and `stdev` aggregates produce doubles, and `min` and `max` aggregates can produce varying types depending on what type of column they're applied to.  As a result, we should cast all aggregate results to String so that `describe()`'s output types match its declared output schema.
