    Updated the py_pkgs lookup plugin for multi source

    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.
