Flip xmpp connections upon router id change

When router id change is detected, we already flip all bgp peerings. Similarly
we should also flip all xmpp agent connections so that any routes originated
based on old router-id gets deleted and new ones based on the modified
router-id is re-generated correctly (especially in multicast areas)
