      Description of problem:

      This is an issue that IBM Cloud found and it likely effects Power VS. See https://issues.redhat.com/browse/OCPBUGS-28870
      
      Install a private cluster, the base domain set in install-config.yaml is same as another existed cis domain name. 
      After destroy the private cluster, the dns resource-records remains. 

      Version-Release number of selected component (if applicable):

      4.15

      How reproducible:

      Always

      Steps to Reproduce:

      1.create a DNS service instance, setting its domain to "ibmcloud.qe.devcluster.openshift.com", Note, this domain name is also being used in another existing CIS domain.
      2.Install a private ibmcloud cluster, the base domain set in install-config is "ibmcloud.qe.devcluster.openshift.com"
      3.Destroy the cluster
      4.Check the remains dns records     

      Actual results:

      $ ibmcloud dns resource-records 5f8a0c4d-46c2-4daa-9157-97cb9ad9033a -i preserved-openshift-qe-private | grep ci-op-17qygd06-23ac4
      api-int.ci-op-17qygd06-23ac4.ibmcloud.qe.devcluster.openshift.com 
      *.apps.ci-op-17qygd06-23ac4.ibmcloud.qe.devcluster.openshift.com 
      api.ci-op-17qygd06-23ac4.ibmcloud.qe.devcluster.openshift.com

      Expected results:

      No more dns records about the cluster

      Additional info:

      $ ibmcloud dns zones -i preserved-openshift-qe-private | awk '{print $2}'   
      Name
      private-ibmcloud.qe.devcluster.openshift.com 
      private-ibmcloud-1.qe.devcluster.openshift.com 
      ibmcloud.qe.devcluster.openshift.com  
      
      $ ibmcloud cis domains
      Name
      ibmcloud.qe.devcluster.openshift.com
      
      When use private-ibmcloud.qe.devcluster.openshift.com and private-ibmcloud-1.qe.devcluster.openshift.com as domain, no such issue, when use ibmcloud.qe.devcluster.openshift.com as domain the dns records remains.
