Significant rework for RPM/python
    
    This is a significant rework of the script. Too many to try and
    break up into small parts. Highlights:
    
    - Now generates RPMs for installation
    - Parts re-worked in python
    - Retries if there are merge conflicts
    - Uses koji for getting more information
    
    Hopefully this will be the last big drop and other changes will
    be smaller.
