replace partner-bugzilla with bugzilla.stage https://partner-bugzilla.redhat.com is being removed, and https://bugzilla.stage.redhat.com is provided instead. Replace all configuration and code with the new URL. Require python-bugzilla >= 3.1.0, because it contains an important fix for bugzilla.stage handling.
