Comment 1 for bug 1840421

From looking at the code, the edge charms set a flag in the cloud-provider config files that says that Octavia is used as the lbaas. The logic is then different for Octavia vs non-Octavia Lbaas and skips the security group issue we are having .... or at least that's the theory as i can't get them to work!

See: https://github.com/charmed-kubernetes/layer-kubernetes-common/blame/master/lib/charms/layer/kubernetes_common.py#L456

and how the logic in the openstack cloud provider is linked to this:
