Follow up "Support ovs/openflow_processed_per_port configuration option"

This is follow-up of ebd50d6444 and
addresses the following points.

- Add missing release note
- Add unit test assertion of the new resource
- replace the hard-coded default by os_service_default fact to avoid
  additional maintenance effort to sync the default
