Disabling SSL in charms

Hey good people,

I am trying to disable SSL for an application (eg: swift-proxy or keystone). But I am unable to find such an option in the charm. Has anyone ever tried disabling SSL for openstack services using charms?

Note: The only way I was able to do this was by removing all the units, removing application and then finally reading the units with new ha_bundle.yml (which did not have ssl_cert/ssl_key).

Thank you!
