How to automatically run upload.py when it doesn't have option to pass the password

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Put the upload.py command in a shell script
2. It takes auth from saved cookie
3. But in few days the cookie expires and it is throwing error (I had to 
manually go and rerun it)

What is the expected output? What do you see instead?
There should be a way to pass the password

What browser are you using?  What version? On what operating system?
Google Chrome | Linux

At what URL are you accessing Rietveld?  (e.g. codereview.appspot.com)
Please note if you are using the Google Apps Labs version (e.g.
codereview.<yourdomain>).

Technically it's a dupe of issue 385, using OAuth2 should fix the problem. But 
OAuth2 is not used by default AFAIK. This needs to be fixed.
