The py_pkgs lookup plugin will now handle multiple sources. This change
was needed to enable the system to allow for overrides of repo_package
resources and general python packaging as found throughout the stack.
The module has precedence as it loads / searches for packages and he item
loaded last is the one that has the most precedence.
The repo-build play has been updated to now search for compatible packages
in the main playbook directory, the root ansible role directory and the
user_variables file.
Documentation has been added regarding this capability and how to override
and set items to meet the needs of the deployment.
