Cleanup script does not consider cluster name when look for cluster API load balancer

Created by: matofeder

When e.g. two CAPI clusters (with different names) want to share one OpenStack project and then one of them should be removed, the cleanup script wrongly removes all cluster API load balancers that contain clusterapi string. The cleanup script does not consider the cluster name, see here.

Suggested solution: Consider cluster name in the cluster API load balancer filtering
