Add auth_config to api.image.inspect_distribution

This is an excerpt from docker-py 4.4.4 needed to check if a given image
exists in an authenticated registry.

Test scenario:

- Generated a new build with this change
- Installed the platform without errors
- Installed stx-openstack without errors
- Changed the docker-registry url and called a sm-restart for
sysinv-conductor to force the upgrade-static-images.yml to run
- Log: http://paste.openstack.org/show/807236/
