Subject: [PATCH] A load balancer should be updated if a service's UID has
 changed.

The load balancer's name is determined by the service's UID. If the
service's UID has changed (presumably due to a delete and recreate),
then we need to recreate the load balancer as well to avoid eventually
leaking the old one.
