[occm] Shared loadbalancer should not be renamed.

[kratisto]

Hello,

Is this a BUG REPORT or FEATURE REQUEST?:
/kind bug

While testing shared loadbalancers, i think i discovered a regression since this PR.

A shared loadbalancer is renamed due to this if. What happens here is :

We enter the ensureOctaviaLoadBalancer function as clusterb with a shared loadbalancer named : kube_service_clustera_kns_fakeservice

At the end we can see the cluster has been renamed : kube_service_clusterb_kns_fakeservice.

And we have the event :
Warning LoadBalancerRename Loadbalancer fakeloadbalancerid has a name of kube_service_clustera_kns_fakeservice with incorrect cluster-name component. Renaming it to kube_service_clusterb_kns_fakeservice.

The tags has been changed too :
["kube_service_clustera_kns_fakeservice","clustera","kube_service_clusterb_kns_fakeservice"]
become ["kube_service_clusterb_kns_fakeservice","clustera","kube_service_clusterb_kns_fakeservice"]

I created a test that reproduce the regression.

Didn't test if it's the case , but i suspect that if we launch a third time as clusterc , the shared loadbalancer will be renamed again.
So the ownership will be for the last runner of ensureOctaviaLoadBalancer
