Upgrade N->O Nova services launch with newton tag and not ocata (systemd issue)

[Grelaud]

Upgrade Newton 14.1.1 to Ocata 15.1.0

Nova services are not launched with new ocata tag (see attachment).

Exemple:
"sytemctl status nova-conductor" give a warning:

Warning: nova-conductor.service changed on disk. Run 'systemctl daemon-reload' to reload units.

# systemctl daemon-reload
# sytemctl restart nova-service

And nova service are launched with the good tag...

In nova role, task nova_init_systemd.yml, in the last play "Place the systemd init script", we use notify to restart nova services, we can also notify a reload systemd.

- name: Place the systemd init script
  template:
    src: "nova-systemd-init.j2"
    dest: "/etc/systemd/system/{{ item.value.service_name }}.service"
    mode: "0644"
    owner: "root"
    group: "root"
  with_dict: "{{ nova_services }}"
  when:
    - inventory_hostname in groups[item.value.group]
    - "{{ item.value.condition | default(true) }}"
  notify:
    - Reload systemd daemon <<<<<<<<<<<<<<<<
    - Restart nova services

And add in handlers/main.yml

- name: Reload systemd daemon
  command: "systemctl daemon-reload"

This should be fixed with latest Ocata version. See here: https://review.openstack.org/#/c/452327/
