Comment 5 for bug 2049551

This code should have handled the deprecation of the endpoint_type setting:

https://opendev.org/openstack/octavia/src/commit/5750e4512d622450f6ecab1c7001ebd5637e0d53/octavia/common/config.py#L948-L952

basically, it sets the [neutron]/valid_interfaces setting with the value of [neutron]/endpoint_type (as a list), the update should have been straighforward, I'm going to check what could happen there
