Goal: 

The targeted scenario requires 3 more nodes to play the ceph cluster. We therefore need to modify the custom-reproducer playbook to:

1. fix the MAC addresses for those three new nodes
2. ensure those new nodes are created

Needed modifications:

• It may require changing the gitlab-ci pipeline to use another environment file than the current "hci" one.
• It may require changing the documentation to reflect the new deployed virtual infrastructure

Acceptance Criteria:

• The custom reproducer deploys three more nodes able to play the ceph cluster.
• Names as well as MAC addresses are fixed.
