+++ This bug was initially created as a clone of Bug #1784063 +++

Description of problem:
When "noobaa: true" is configured in the migration controller, the operator fails if "s3" service has no "hostname" field present in its status because of the LoadBalancer.



Version-Release number of selected component (if applicable):
CLUSTER (Azure) OCP4:
$ oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS

How reproducible:
Always

Steps to Reproduce:
1. Install a OCP4 4.2 cluster in Azure
2. Install the cam operator (and ocs4 operator) from 1.0.1 osbs.
3. Create a MigrationController with noobaa: true
4. Verify that an external load balancer is being used, with no "hostname" attribute in the "s3" service
 
  oc get svc s3 -o yaml -n openshift-migration


Actual results:
There is an erro in CAM operator:

PLAY RECAP *********************************************************************



Expected results:
There should be no error in the operator's logs, and the noobaa bucket should be added without problems

Additional info:

Ansible is looking for a hostname in the service's status, and there is no hostname in it

oc get svc s3 -o yaml -n openshift-migration

"status": {"loadBalancer": {"ingress": [{"ip": "52.238.254.172"}]}}}]}
