Webhook config cleanup (#1200)

* webhook: remove autogenerated misleading labels

Autogenerated Service contains labels which do no correspond
existing ones:

app.kubernetes.io/name: service
app.kubernetes.io/instance: webhook-service
app.kubernetes.io/component: webhook

Remove from both kustomize and bundle manifests.
