Return a dict without any of the __pub* keys (or any other keys starting
    with a dunder) from the kwargs dict passed into the execution module
    functions. These keys are useful for tracking what was used to invoke
    the function call, but they may not be desirable to have if passing the
    kwargs forward wholesale.

    Usage example:

    .. code-block:: python

        kwargs = __utils__['args.clean_kwargs'](**kwargs)

def clean_kwargs(**kwargs):
