Unable to configure OpenStack

Hey, I am on develop branch. I got access to OpenStack which is at https://xxx:13000/v2.0. If I try to add this URL I get 404. If I provide /v3/auth/tokens then it’s again 404 so I guess my instance is too old. And finally when I try to put / then I get undefined methodlist_tenants’` error. I do see couple of bugs for this error reported on fog-openstack. I guess OpenStack is currently unusable with Foreman?

There’s a patch I would like to test, but I guess I’d need to fix fog-openstack first. Any workarounds? https://github.com/theforeman/foreman/pull/6282/files
