[SPARK-17603] [SQL] Utilize Hive-generated Statistics For Partitioned Tables ### What changes were proposed in this pull request? For non-partitioned tables, Hive-generated statistics are stored in table properties. However, for partitioned tables, Hive-generated statistics are stored in partition properties. Thus, we are unable to utilize the Hive-generated statistics for partitioned tables. The statistics might not be gathered for all the partitions in Hive. For partial collection, we will not utilize the Hive-generated statistics. ### How was this patch tested? Added test cases.
