Description of problem:

When upgrading Octavia from OSP13 to OSP16 the CNO checks if tagging is supported and if it's tries to look for an API load balancer with tag. However, the existent LB was created with OSP13, which does not support tagging and so the tagging is added on description. The CNO then tries to create a new LB API and fails as the address is already in use.

CNO logs:
2020/02/28 16:21:14 Failed to reconcile platform networking resources: failed to create OpenShift API loadbalancer: failed to create LB: Internal Server Error
