Migrate VRFRouteConfiguration and Layer2NetworkConfiguration to Sylva

Recipe IDio.moderne.kubernetes.sylva.migrate.dasschiff.MigrateLowLevelNetworkConfigToIntent
Artifactorg.openrewrite.recipe:rewrite-kubernetes

Rewrite Das Schiff VRFRouteConfiguration and Layer2NetworkConfiguration resources into the network-connector.sylvaproject.org intent resources that replace them. Each becomes two: a VRF and a Destination, or a Network and a Layer2Attachment. Both kinds move here rather than in a recipe each, because a VRF moves whole or not at all. A resource whose meaning would change is reported rather than approximated.
