Bug 1659479

+++ This bug was initially created as a clone of Bug #1656690 +++

Description of problem:
neutron/auth_url has public endpoint URL in nova.conf.

In my KVM lab, an auth_url parameter in nova.conf has different value from others.

NOTE: Please see the line pointed by 'HERE'

The assignment comes from following line in puppet/services/nova-base.yaml.
~~~
    226           nova::network::neutron::neutron_auth_url: {get_param: [EndpointMap, KeystoneV3Admin, uri]}
~~~
Upstream T-H-T also has the same templates.
It looks that the option should align to other components.

Version-Release number of selected component (if applicable):
Current T-H-T

How reproducible:
Every deployment.

Steps to Reproduce:
1. Deploy overcloud.
2. Check the configuration with grep -e ^auth_url /var/lib/config-data/puppet-generated/*/etc/*/*.conf
3.

Actual results:
auth_url in neutron section has a admin endpoint value.

Expected results:
auth_url in neutron section has a internal api endpoint value.
