See serving #11906
See https://docs.google.com/document/d/1XE7UzgQlVVtAb7ULSqOyKCaIHtm8zMF35ainp1JmwyY/

This issue focuses on adding DataPlan-Trust support for Activator and Queue including options for:
dataplane-trust = "minimal" (common names for all namespaces)
dataplane-trust = "enabled" (per namespace)
dataplane-trust = "mutual" mTLS

If dataplane-trust = "mutual", QP will require a Client certificate and verify the Client certificate having the name "kn-routing-0"
