Chef::Provider::Package::Dnf#python_helper

Most of the magic in this class happens in the python helper script.  The ruby side of this
provider knows only enough to translate Chef-style new_resource name+package+version into
a request to the python side.  The python side is then responsible for knowing everything
about RPMs and what is installed and what is available.  The ruby side of this class should
remain a lightweight translation layer to translate Chef requests into RPC requests to
python.  This class knows nothing about how to compare RPM versions, and does not maintain
any cached state of installed/available versions and should be kept that way.
