[SPARK-16905] SQL DDL: MSCK REPAIR TABLE
## What changes were proposed in this pull request?
MSCK REPAIR TABLE could be used to recover the partitions in external catalog based on partitions in file system.
Another syntax is: ALTER TABLE table RECOVER PARTITIONS
The implementation in this PR will only list partitions (not the files with a partition) in driver (in parallel if needed).
## How was this patch tested?
Added unit tests for it and Hive compatibility test suite.
