[warm reboot] save configuration after warm reboot (#3200)

* [warm reboot] save configuration after warm reboot

After warm reboot, save a copy of in memory database to config_db.json,
upgrade procedure might have removed config_db.json to force new image
to reload minigraph. However, reload minigraph is skipped during warm
reboot. Missing config_db.json would cause device to fault in next
non-upgrading cold/fast reboot.
