network: Gather OVN-Kubernetes UDN CRs

The ClusterUserDefinedNetwork (CUDN) is cluster-scoped.
The UserDefinedNetwork (UDN) is namespace-scoped.
Both CRDs are installed by cluster-network-operator [1].

Creating CUDN CR result with a NetworkAttachmentDefinition (NAD) CR
being created according to the CUDN CR 'spec.network', in each selected
namespaces according to the CUDN CR 'spec.namespaceSelector'.
Creating UDN CR result in NAD CR being created at the same namespaces as the
UDN CR resides according to its spec.

Collect CUDN and UDN CRs.

Having CUDN and UDN CRs collected enable troubleshooting OVN-Kubernetes
user-defined networks in case of miss-configurations or env issues.
