Cloned from launchpad bug 1632538.

Description:

Enabling SSL on the Undercloud using generate_service_certificate results in all Nova services on the undercloud (api, cert, compute, conductor, scheduler), all failing with errors similar to the following:

I believe the failure happens inside the [neutron] section of /etc/nova/nova.conf.  

This does not look related to the scheme (https) being used as the result of enabling SSL because doing a one-off test with the openstack-nova-conductor service after changing the schema to http results in the same startup failure.

Another one-off test substituting an IP address instead of a FQDN inside of nova.conf with the openstack-nova-conductor service as before results in openstack-nova-conductor starting properly but eventually failing with a connection-related failure due to the one-off data used (an IP address of 1.2.3.4).
