* CentOS 7 RPM GPG key

- Removed hardcoded yum repository configuration in favor of
  commands dynamically generated based on repo-url and repo-file
  arguments. We maintain a sane default set of repositories.
- Added generic rpm_setup_config parameter to add support for
  installing .rpm or .repo files before building containers.

By ignoring the appropriate tests that pep8 does we can properly run
*most* of the pep8 tests on all of our modules allowing for a more
consistent coding style.

Convert config creation from a playbook to an action_plugin. This
reduces the complexity and confusion while retaining the same augment
structure and flexibility.

This allows us to remove the 0-byte files as requirements. They will
still be used if they are present (this means we require additional
documentation around them).
