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.

Note that for CI, KubevirtIpamController will not be able to deploy
without Multus (that deploys the net-attach-def CRD) alongside it, or
the net-attach-def deployment will fail, with error:
`could not apply (k8s.cni.cncf.io/v1, Kind=NetworkAttachmentDefinition)
default/primary-user-defined-network: could not retrieve existing
(k8s.cni.cncf.io/v1, Kind=NetworkAttachmentDefinition)
default/primary-user-defined-network: no matches for kind
"NetworkAttachmentDefinition" in version "k8s.cni.cncf.io/v1"`
