Update setup for easier packaging and publish a tarball

Changes have been made to the setup.cfg file so that this repository
can be packaged (rpm, deb, etc) easier. This change also updates the
project layout so that we're publishing the code to tarballs, which
again, makes it easy to package config_template for distros.
