572	Move Columns from MediaEntry to ProcessingMetaData	Elrond		"There is a new table for data used while (or at the end of) processing. It's currently only used for the callback url. We should use it for more things. So I propose to move various columns from `MediaEntry` into `ProcessingMetaData`.

Possible columns:
* transcoding_progress
* queued_task_id
* queued_media_file (*)
* fail_error (*)
* fail_metadata (*)

After a successful processing, none of these are needed.
After a failed processing, those with (*) might be needed for various reasons. We should rethink that part maybe anyway."	enhancement	new	trivial		programming		bitesized	Christopher Allan Webber
