If an infra-id (which is uniquely generated by the installer) is reused the installer will fail with:

level=info msg=Creating private Hosted Zone
level=error msg=failed to fetch Cluster: failed to generate asset "Cluster": failed to create cluster: failed provisioning resources after infrastructure ready: failed to create private hosted zone: error creating private hosted zone: HostedZoneAlreadyExists: A hosted zone has already been created with the specified caller reference.


Users should not be reusing installer state in this manner, but we do it purposefully in our ipi-install-install step to mitigate infrastructure provisioning flakes:

https://steps.ci.openshift.org/reference/ipi-install-install#line720

We can fix this by ensuring the caller ref is unique on each invocation.
