[SPARK-18949] [SQL] [BACKPORT-2.1] Add recoverPartitions API to Catalog
### What changes were proposed in this pull request?
This PR is to backport https://github.com/apache/spark/pull/16356 to Spark
2.1.1 branch.
----
Currently, we only have a SQL interface for recovering all the partitions
in the directory of a table and update the catalog. `MSCK REPAIR TABLE` or
`ALTER TABLE table RECOVER PARTITIONS`. (Actually, very hard for me to remember
`MSCK` and have no clue what it means)
After the new "Scalable Partition Handling", the table repair becomes much
more important for making visible the data in the created data source
partitioned table.
Thus, this PR is to add it into the Catalog interface. After this PR, users
can repair the table by
```Scala
spark.catalog.recoverPartitions("testTable")
```
### How was this patch tested?
Modified the existing test cases.
