There is no option to set ParquetWriterConfig when create new ParquetSink instance

[StdCarrot]

There is no params to set ParquetWriterConfig when create new ParquetSink instance. I couldn't set it after created. Because some variables which for it were defined as val. And almost components were in closure. How can I do that? Or, when you change this?

It'll be changed for 1.3.0 final so that you can configure all options.
