feat: add configurable loadbalancer network

[oblazek]

Previously when loadbalacer was created it used the same network/subnet as the control plane nodes for the VIP. This was not always the right assumption as some users might want to be able to customize this according to their env.

This commit fixes the above by adding two fields into OpenStackClusterSpec/Status two fields network and subnets under APIServerLoadBalancer so that user can define which network/subnet to use for allocation of the loadbalancer.

apiVersion: infrastructure.cluster.x-k8s.io/v1alpha8
kind: OpenStackCluster
metadata:
  name: {{ capi_cluster_name }}
spec:
  cloudName: {{ capi_cluster_os_cloud }}
  identityRef:
    kind: Secret
    name: test3-cloud-config
  managedSecurityGroups: true
  apiServerLoadBalancer:
    enabled: true
    network:
      name: vip-net-ulab1
    subnets:
      - name: ulab1-ipv4-1
status:
  apiServerLoadBalancer:
    id: 808239dc-064f-402e-bd7d-ca667157a76c
    internalIP: 10.248.11.161
    ip: ""
    loadBalancerNetwork:
      id: 65f6a910-3968-46c0-8f72-e4f171476670
      name: vip-net-ulab1
      subnets:
      - id: 5b4e2c9b-1ab9-4510-87a4-6d2301e16e77

Hi @oblazek. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
