In CM-319, we've added the e2e tests for customizing API Sever and Ingress certificates in AWS clusters.
For this ticket, we are going to expand the tests to cover more cloud platforms, like GCP.
We could create the corresponding clusterissuer based on the $CLUSTER_TYPE:
- AWS -> use the AWS Route53 as the ACME dns01 provider
- GCP -> use the GCP CloudDNS as the ACME dns01 provider
