Comment 4 for bug 1643197

Hi, I think there should be no dependencies between "how magnum connects to the API ?" which is the parameters specified in magnum.conf and "how instances can reach the API".

It really depends on the customer deployment and as Jean-Philippe Evrard mentionned for Openstack Ansible, a majority of services use internalURL on a management network to reach the API. But Public URL for API might be on a different external network, and this network should be use for instances to connect to the API

So the parameters should not be linked together, there sould be another options to specify how instance connect to the API, independent from Magnum service itself
