When pods that run on host network are recreated, if they are pointed by a svc, the removal of the load balancer member is ignored, as right now only the IP of the pod is considered and as pods are using host networking the IPs match.

And at the end it makes the kuryr-controller to restart due to a timeout adding that member:
