Replace a dead node

1. The ansible/playbooks/replace_machine_remove_machine_from_cluster.yaml playbook can remove a node in the cluster. For this, the machine_to_remove should be set to the hostname to remove.
   The below command should be launch in the ansible project.

   cqfd run ansible-playbook -i /path/to/inventory.yaml -e machine_to_remove=HOSTNAME playbooks/replace_machine_remove_machine_from_cluster.yaml

2. A new hosts should be install with the ISO installer and a new IP address. Make the connections between hosts.
3. Restart the playbook to configure the cluster (more details here).
