    Configure insecure registries before Pacemaker-managed image pulls

    Service templates like mysql-pacemaker-puppet.yaml pull fresh
    container images in step 2 of the upgrade tasks. In case they come
    from an allowed insecure registry, the insecure registries setting
    must be in place by step 1. We do just that by reusing the "install
    and configure Podman" part of host_prep_tasks.
