Description of problem:

Both ansible.utils and ansible.netcommon has been recently updated:

• ansible.netcommon:8.0.0
• ansible.utils:6.0.0

These versions are applying a warning message that has been shown on CI for some time:

[DEPRECATION WARNING]: Use 'ansible.utils.next_nth_usable' module instead. This feature will be removed from ansible.netcommon in a release after 2024-01-01.

The current playbooks are using next_nth_usable without specifying the collection: 

1. https://github.com/openshift/installer/blob/main/upi/openstack/inventory.yaml#L57
2. https://github.com/openshift/installer/blob/main/upi/openstack/inventory.yaml#L63
3. https://github.com/openshift/installer/blob/main/upi/openstack/network.yaml#L23

The fix would be to replace "next_nth_usable" by "ansible.utils.next_nth_usable".
