[SPARK-16202][SQL][DOC] Correct The Description of CreatableRelationProvider's createRelation
#### What changes were proposed in this pull request?
The API description of `createRelation` in `CreatableRelationProvider` is misleading. The current description only expects users to return the relation.
```Scala
trait CreatableRelationProvider {
def createRelation(
sqlContext: SQLContext,
mode: SaveMode,
parameters: Map[String, String],
data: DataFrame): BaseRelation
}
```
However, the major goal of this API should also include saving the `DataFrame`.
Since this API is critical for Data Source API developers, this PR is to correct the description.
#### How was this patch tested?

Closes #13903 from gatorsmile/readUnderscoreFiles.
