uni01alpha - update network-values values.j2 for ironic

[hjensas]

In PR: openstack-k8s-operators/architecture#211 the DT is updated to configure Ironic so that it can be used beyond running API tempest test cases.

It adds a network bridge "ironic", and this is attached to the ironic service pods, OVN. Also Nova is configured to run a compute pod with the ironic driver.

This PR updates the values.j2 for the uni01alpha job to work with PR#211.
We also need: https://gitlab.cee.redhat.com/ci-framework/ci-framework-jobs/-/merge_requests/282

Not all networks are neccecarily connected to EDPM nodes. Allow generating network-values for networks without netconfig. For example:

    ironic:
      network: "172.20.254.0/24"
      tools:
        metallb:
          ranges:
            - start: 80 end: 90 mtu: 1500
