hyukjinkwon 9e204c62c6 [SPARK-15840][SQL] Add two missing options in documentation and some option related changes 
## What changes were proposed in this pull request?

This PR

1. Adds the documentations for some missing options, `inferSchema` and `mergeSchema` for Python and Scala.

2. Fiixes `[[DataFrame]]` to ```:class:`DataFrame` ``` so that this can be shown

  (Please refer [the latest documentation](https://people.apache.org/~pwendell/spark-nightly/spark-master-docs/latest/api/python/pyspark.sql.html))

3. Moves `mergeSchema` option to `ParquetOptions` with removing unused options, `metastoreSchema` and `metastoreTableName`.

  They are not used anymore. They were removed in e720dda42e and there are no use cases as below:

  ```bash
  grep -r -e METASTORE_SCHEMA -e \"metastoreSchema\" -e \"metastoreTableName\" -e METASTORE_TABLE_NAME .
  ```

  ```
  ./sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/parquet/ParquetFileFormat.scala:  private[sql] val METASTORE_SCHEMA = "metastoreSchema"
  ./sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/parquet/ParquetFileFormat.scala:  private[sql] val METASTORE_TABLE_NAME = "metastoreTableName"
  ./sql/hive/src/main/scala/org/apache/spark/sql/hive/HiveMetastoreCatalog.scala:        ParquetFileFormat.METASTORE_TABLE_NAME -> TableIdentifier(
```

  It only sets `metastoreTableName` in the last case but does not use the table name.

4. Sets the correct default values (in the documentation) for `compression` option for ORC(`snappy`, see [OrcOptions.scala#L33-L42](3ded5bc4db/sql/hive/src/main/scala/org/apache/spark/sql/hive/orc/OrcOptions.scala (L33-L42))) and Parquet(`the value specified in SQLConf`, see [ParquetOptions.scala#L38-L47](3ded5bc4db/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/parquet/ParquetOptions.scala (L38-L47))) and `columnNameOfCorruptRecord` for JSON(`the value specified in SQLConf`, see [JsonFileFormat.scala#L53-L55](4538443e27/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/json/JsonFileFormat.scala (L53-L55)) and [JsonFileFormat.scala#L105-L106](4538443e27/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/json/JsonFileFormat.scala (L105-L106))).

## How was this patch tested?

Existing tests should cover this.
