Remove D-Bus dependency from Manager
Here are the main changes:
1. Cleanup Manager::CreateService and Manager::RemoveService API
to remove D-Bus dependency.
1. Use refptr for Service since it will be maintained by both
Manager and its adaptor.
2. Move the monitoring of the service creator/owner to the adaptor,
since the DBusServiceWatcher is D-Bus specific.
