Public bug reported:

unpause server API policy is default to admin_or_owner[1] but API is
allowed for everyone.

We can see the test trying with other project context can access the API
- https://review.opendev.org/#/c/716161//1

This is because API does not pass the server project_id in policy target
- https://github.com/openstack/nova/blob/eb6bd04e4c27c70b5239dbe7c17607b37f4e87dd/nova/api/openstack/compute/pause_server.py#L58

and if no target is passed then, policy.py add the default targets which is nothing but context.project_id (allow for everyone try to access)
