    Fix neutron api TLS issues

    There are two tls issues currently in neutron:
    A) neutron_api is doing bind mounting tls certs directly from the host and then chowning them from then container.
    "Source": "/etc/pki/tls/private/ovn_neutron_client.key",
    "Destination": "/etc/pki/tls/private/ovn_neutron_client.key",

    "Source": "/etc/pki/tls/certs/ovn_neutron_client.crt",
    "Destination": "/etc/pki/tls/certs/ovn_neutron_client.crt",

    And then it thinks it can chown it inside the container via the kolla script:
    [root@controller-0 stdouts]# more /var/lib/kolla/config_files/neutron_api.json
    ...
            {
                "optional": true,
                "owner": "neutron:neutron",
                "path": "/etc/pki/tls/certs/ovn_neutron_client.crt",
                "perm": "0644"
            },
            {
                "optional": true,
                "owner": "neutron:neutron",
                "path": "/etc/pki/tls/private/ovn_neutron_client.key",
                "perm": "0644"
            }

    What needs to happen here is that we drop the direct bind mounts, and copy in the certs via kolla. Just like galera is doing.

    Tested and with this patch I correctly get a Train/OSP16 TLS everywhere
    deployment with a working neutron:
    Before:
    (overcloud) [stack@undercloud-0 ~]$ openstack network list
    HttpException: 503: Server Error for url: https://overcloud.redhat.local:13696/v2.0/networks, No server is available to handle this request.: 503 Service Unavailable

    After:
    (overcloud) [stack@undercloud-0 ~]$ openstack network list
    (overcloud) [stack@undercloud-0 ~]$

    B) The logging in the neutron_server_tls_proxy container is not persisted to the host

    Before:
    [root@controller-0 ~]# ls -l /var/log/containers/httpd/neutron-api/
    [root@controller-0 ~]#

    After:
    [root@controller-0 ~]# ls -l /var/log/containers/httpd/neutron-api/
