What changes were proposed in this pull request?
Currently there are some code duplicates in continuous Parquet writes (as in Structured Streaming) and non-continuous writes; see ParquetFileFormat#prepareWrite() and ParquetFileFormat#ParquetOutputWriterFactory.
This may lead to inconsistent behavior, when we only change one piece of code but not the other.
By extracting the common code out, this patch fixes the inconsistency. As a result, Structured Streaming now also enjoys SPARK-15719.
How was this patch tested?
Just code refactoring without any logic change; this should be covered by existing suites.
