Quay CR deployment with externalAccess as LoadBalancer missing LB DNS on GCE

Description:
This is an issue found when deploy Quay CR on Google Cloud Platform, when set externalAccess as LoadBalancer in Quay CR file, Quay CR deployment can be deployed successfully, but the LoadBalancer does not has DNS name, checked in Quay config-app, the hostname is grayed and set as "104.197.89.235", after change some configurations, it was failed to save configurations, report error message "Supported names "quay-enterprise, quay-enterprise@1587885947" in SSL cert do not match server hostname "104.197.89.235"", refer to attached screenshots.

Expected Results:
The LoadBalancer generated by Operator on GCE should give valid DNS name, like the same behavior on AWS; and the Quay hostname in Config-app should use the correct hostname rather than IP address.

Actual Results:
The LoadBalancer generated by Operator on GCE only give external IP without using correct loadbalancer DNS name, in quay config-app, the Quay hostname is IP address.
