Scheduler driver should use Service object

[Sylvain Bauza]

There is still one place where the Scheduler does direct DB access instead of using the oslo.versionedobjects layer

https://github.com/openstack/nova/blob/af2d6c9576b1ac5f3b3768870bb15d9b5cf1610b/nova/scheduler/driver.py#L54

Instead of calling db.service_get_all_by_topic(), it should call objects.ServiceList.get_by_topic()

@shravya-g90: It looks like we both grabbed this bug an hour ago. I didn't notice you were also working on it until I refreshed by browser just now. My apologies.

    direct db call to get all services by topic.
