Is this a BUG REPORT or FEATURE REQUEST?:

/kind bug

What happened:
If a service was previously of type LoadBalancer, then was switched to another type (for instance NodePort) and the service is switched again to LoadBalancer : the LoadBalancer fails to be created because the LoadBalancer cannot be found (based on the ID from the annotations).

What you expected to happen:
The LoadBalancer should be created without any issue

How to reproduce it:

• create a svc of type LoadBalancer
• wait for the LB to be ready
• switch the svc to ClusterIP or NodePort
• wait for the LB to be deleted
• switch against the svc to LoadBalancer
• It does not work because there are these annotations remaining:

metadata:
  annotations:
    loadbalancer.openstack.org/load-balancer-address: 185.22.97.21
    loadbalancer.openstack.org/load-balancer-id: 5b268775-d01c-487d-83c6-f77308a9500a

Environment:

• openstack-cloud-controller-manager(or other related binary) version: 1.31.1
• OpenStack version: Zed
• Others: No
