Code rewrite and Python3 support
The code has been rewritten in multiple classes and files for better
readability and maintainability. You should now also use Python3 to run
the scripts. Some of the variables in the config files have moved to
other sections. The pushgateway parameter moved to the [varia] section
of the rapid environment file.
