Create NetworkInstance

cat <<EOF | kubectl apply -f -
apiVersion: ipam.nephio.org/v1alpha1
kind: IPPrefix
metadata:
  name: net1-prefix1
  labels:
    nephio.org/gateway: "true"
spec:
  prefix: 10.0.1.1/24
  network: net1
  networkInstance: vpc-1
EOF
networkinstance.ipam.nephio.org/vpc-1 created

But creating the ipprefix fails:

/k8s-ipam # cat <<EOF | kubectl apply -f -

> metadata:

> EOF
