[SPARK-6369] [SQL] Uses commit coordinator to help committing Hive and Parquet tables

This PR leverages the output commit coordinator introduced in #4066 to help committing Hive and Parquet tables.

This PR extracts output commit code in `SparkHadoopWriter.commit` to `SparkHadoopMapRedUtil.commitTask`, and reuses it for committing Parquet and Hive tables on executor side.

TODO

- [ ] Add tests
