Okay, my guess is that both oslo_config and oslo_log are trying to
register_cli_options. I have to create a configuration object for
oslo_log to work, and it means CLI options are registered once.
Later on, when I'm calling log.register_options(), it is conflicting
with previous registration.

So, I'm doubting whether these two packages have been tested together?
