I've got two guesses why it does not work properly:

1. Savanna does not consume config file at all and the defaults (by
coincidence) do not work for swift only.

2. you invoke swift_helper.get_swift_configs() at the top level of some
module like that:
      SWIFT_CONFIG = swift_helper.get_swift_configs()
The oslo.config is not initialized at module load time (that is true for
any module), so that is why you see the defaults instead of the supplied
values.

Still, if you share the code, some other ideas might pop-up.
