[SPARK-15472][SQL][Streaming] Add partitioned `csv`, `json`, `text` format
support for FileStreamSink
## What changes were proposed in this pull request?
This patch adds partitioned `csv`, `json`, `text` format support for
`FileStreamSink`.
For each format, this patch adds a dedicated `OutputWriterFactory`, which
would return a dedicated `OutputWriter` writing data without using an
`OutputCommitter`. This is the same approach taken by
[SPARK-14716](https://github.com/apache/spark/pull/12409) in which we had added
partitioned `parquet` format support.
## How was this patch tested?
`FileStreamSinkSuite` is expanded to cover the added `csv`, `json`, `text`
format:
```scala
test(" csv - unpartitioned data")
test("json - unpartitioned data")
test("text - unpartitioned data")
test(" csv - partitioned data")
test("json - partitioned data")
test("text - partitioned data")
test(" csv - unpartitioned writing and batch reading")
test("json - unpartitioned writing and batch reading")
test("text - unpartitioned writing and batch reading")
test(" csv - partitioned writing and batch reading")
test("json - partitioned writing and batch reading")
test("text - partitioned writing and batch reading")
```
