Document stdout json setting

[fcasson]

In job json we can have this key value pair

  "stdout": "/jetto/runs/prom/jetto.out"

I think it was a feature (probably I requested but now can't find disussion of it!) that redirects the file to prominence stdout but it might also redirect stdout to that file?

Can't find anything in the docs to remind me

[fcasson]

Either it's not working as intended, or what is intended is not what I needed (I want to to stream a specific custom file to prominence stdout to track run progress)

I think it was to stream the job's stdout to the specified file.

You want to be able to stream a custom file, not stdout?

[fcasson]

Yes
