The scripts were written in bash. Using bash became quite unwieldy.
Python by nature can deal well with yaml and is thus better suited
in dealing with the yaml-based configuration files. This change
rewrites the original scripts staying as close as possible to the
original ones.
Right now, the python scripts call subprocesses a lot to work with
the tools, which were already used before. At least for yaml-
templating there may be better tools that have a python integration,
which could be used in the future.
