      Actual results:

      the dns records of the cluster were left

      Expected results:

      created dns record by installer are all deleted, after destroyed the cluster

      Additional info:

      this block create private cluster later, caused the maximum limit of 5 wildcard records are easily reached. (qe account limitation)
checking the *ingress-operator.log of the failed cluster, got the error: "createOrUpdateDNSRecord: failed to create the dns record: Reached the maximum limit of 5 wildcard records."
