[SPARK-5595][SPARK-5603][SQL] Add a rule to do PreInsert type casting and field renaming and invalidating in memory cache after INSERT
This PR adds a rule to Analyzer that will add preinsert data type casting and field renaming to the select clause in an `INSERT INTO/OVERWRITE` statement. Also, with the change of this PR, we always invalidate our in memory data cache after inserting into a BaseRelation.
