Problem
Since the RequestReply resource needs a trigger to every pod, rather than to the deployment as a whole, we need to create an InitContainer which creates the trigger to the current pod. The trigger should look like:

apiVersion: eventing.knative.dev/v1
kind: Trigger
metadata:
  name: <generated name>
  namespace: <pod namespace>
spec:
  brokerRef: <brokerRef from the RequestReply resource>
  subscriber: <the RequestReply deployment>
  triggers:
    - cesql: "EXISTS <the name of the replyid for the RequestReply resource> AND KN_VERIFY_CORRELATION_ID(<the name of the replyid for the RequestReply resource>, <the secret names for the resource listed out>)"

Persona:
