Environment

Proxmox cluster with three nodes with proxmoxer python modul installed
Ansible playbooks are executed on infra VM (tested with Rocky Linux 8) hosting tftp server, ha proxy as loadbalancer, apache webserver for ignition files

machine-config operator fails to initialize: Solved by running oc delete mc 99-master-okd-extensions 99-okd-master-disable-mitigations after bootstrap finished (okd-project/okd#963)
Ansible vault secret for ssh_pub_key in vars/okd.yml does not work, replace it with a clear-text public key
