Comment 3 for bug 1968091

Found the defaults:

https://github.com/openstack/kolla-ansible/blob/master/ansible/roles/octavia/defaults/main.yml#L301

Now it does make more sense.

There are currently two sec groups. The mgmt-sec-grp (needed for the amphora instances) and health-mgr-sec-grp which is needed for the health-manager nodes when used with network type "tenant".
