Write stdout and stderr to same file

[shaleenb]

Is it possible to write stdout and stderr to the same file?

I tried passing the same file path to both --stdout-file and --stderr-file but the file contained only stderr after execution.

Ahh looks like we overwrite the file with each stream. We'd need to patch papermill to make that work correctly. For now you'd need to send to separate files and merge the files afterwards.
