Bug description:
  [Impact]

  When creating a new "cluster"that overrides the fixed network defined
  in the cluster template, but not the subnet.

  It would be expected that the cluster create request fails with a 400
  error since the client is submitting an invalid request.

  [Environment]

  Focal Ussuri

  [Test Case]

  1. Create a new cluster template WITHOUT a fixed network/subnet set.
  openstack coe cluster template create k8s-cluster-template \
      --image fedora-coreos-32 \
      --keypair testkey \
      --external-network ext_net \
      --flavor m1.small \
      --network-driver flannel \
      --coe kubernetes \
      --fixed-network admin_net \
      --fixed-subnet admin_subnet

  2. Create a new cluster using the template previously created and
  select an existing network

  openstack coe cluster create \
      --cluster-template k8s-cluster-template \
      --timeout 120 \
      --fixed-network private \
      k8scluster

  Expected result

  The cluster gets created

  Actual result:

  The cluster creation fails with the following error:

  $ openstack coe cluster show k8scluster -f json -c faults | jq -r '.faults'
  {
    "default-master": "Resource CREATE failed: BadRequest: resources.kube_masters.resources[0].resources.kube_master_eth0: Invalid input for operation: Failed to create port on network 525df7a4-1aeb-4eae-a37f-432a809a8161, because fixed_ips included invalid subnet 30e1b4ed-811f-4226-a19d-0a56cc72fc10.\nNeutron server returns request_ids: ['req-7a55a40a-3aa3-4a67-8ecf-b2e47ae16a84']",
