Envoy Filter Sidecar to Direct Traffic to Existing Routes or Dynamically Created Routes

For each service that needs dynamic mappings to be created by Skynettes, a Virtual Service is deployed with "creator" pods that know how to create new routes for traffic.

The Envoy filter will intercept traffic from coming into the Pod and either do a 403 redirect to an existing destination, or will allow traffic into the Creator Service.  The Creator service will call the Kubernetes and Istio API to provision the resources needed to handle the request.
