network/kubevirt-ipam-controller: Add new net-attach-def resource

This resource does not belong to kubevirt-ipam-controller, but is
currently piggy-backing this component in order to deploy the primary
user-defined-network net-attach-def [0].

This net-attach-def is deployed on default namespace, as this way it
will be available to all VMs that need to consume it.
