    Return oslo_config Opts to config generator

    We shouldn't be returning keystoneauth Opts to the oslo_config
    generator. Whilst it mostly works these objects are not interchangable
    and it can result in problems. You can see this by entries such as:

      # Warning: Failed to format sample for tenant_name
      # isinstance() arg 2 must be a class, type, or tuple of classes
        and types

    in the currently generated config files.

    Keystoneauth provides a function that returns oslo_config options so
    fetch, process and return those instead.
