contint: python dependency for publish-console.py

publish-console.py is a basic script which is run by the Jenkins slave
present on the CI website.  Given some arguments, it will fetch the
console from the Jenkins master setup locally and write down the console
as a flat file to make it available under /logs/.

The script web requests are handled with python-requests.
