Provide DoFn to convert a Row (record with schema) to a javax.json.JsonObject #18859
Description
This task is about ensuring the generic record of beam can be converted to a more mainstream format (JSON). The usage os javax.json.JsonObject is to ensure it is portable and implementation independent and integrates th emost probably with client libraries (most implementations have a bridge to the jsr anyway)
It will likely lead to provide a Dofn Row -> JsonObject and the opposite.
