Infra/node decommissioning

High overview

This is an overview of the needed tasks to perform when we want to remove a node from our infra :

• Delete/reinstall the (virtual) machine (cleaning up)
  • If hosted within Red Hat DC, update internal ip inventory (Obviously need RH SSO and permission)
• Remove from DNS (public of internal, depending on the case)
• Remove it from Ansible inventory (and search for references for that node in case of)
• Remove it from Zabbix monitoring
