Make sure that when the new image boots up, the component state won't be 'reconciled'. Signed-off-by: Ying Xie <ying.xie@microsoft.com>

You could move code into backup_database(). And consider to adapt the optimization there. #Closed

That would interfere the warm reboot. Syncd warmshutdown uses this table to coordinate operations. Some module might (not today, but maybe in the future) want to leave information to be handled after warm reboot is done. So it would be best to clear the table before any real warm reboot operation started.
