The cluster operator "machine-config" degraded due to MachineConfigPool master is not ready, which tells error like "rendered-master-${hash} not found".

    4.15.0-0.nightly-2023-12-11-033133

    Always. We met the issue in 2 CI profiles, Flexy template "functionality-testing/aos-4_15/upi-on-gcp/versioned-installer-ovn-ipsec-ew-ns-ci", and PROW CI test "periodic-ci-openshift-openshift-tests-private-release-4.15-multi-ec-gcp-ipi-disc-priv-oidc-arm-mixarch-f14".

The Flexy template brief steps:
1. "create install-config" and then "create manifests"
2. add manifest file to config ovnkubernetes network for IPSec (please refer to https://gitlab.cee.redhat.com/aosqe/flexy-templates/-/blame/master/functionality-testing/aos-4_15/hosts/create_ign_files.sh#L517-530)
3. (optional) "create ignition-config"
4. UPI installation steps (see OCP doc https://docs.openshift.com/container-platform/4.14/installing/installing_gcp/installing-gcp-user-infra.html#installation-gcp-user-infra-exporting-common-variables)

    Installation failed, with the machine-config operator degraded

    Installation should succeed.
