Continue along the same line as the recent patch that made the Ruby-related config scripts Python packages and make also the configs/common directory a package. All affected config scripts are updated (hopefully). Note that this change makes it apparent that the current organisation and naming of the config directory and its subdirectories is rather chaotic. We mix scripts that are directly invoked with scripts that merely contain convenience functions. While it is not addressed in this patch we should follow up with a re-organisation of the config structure, and renaming of some of the packages.
