When "mirrorSourcePolicy: NeverContactSource" enabled in ITMS/IDMS, PPO can still verify arch info from source image

 multiarch-tuning-operator.v0.9.0   

 100%   

    1. Create a ITMS with below content
cat <<EOF | oc create -f -
apiVersion: config.openshift.io/v1
kind: ImageTagMirrorSet
metadata:
  name: mto-itms-never-test
spec:
  imageTagMirrors:
  - mirrors:
    - my-fake-itms-never-registry.io/google_containers/redis
    source: gcr.io/google_containers/redis
    mirrorSourcePolicy: NeverContactSource
EOF
    2. wait for mcp finish updated
    3. create a pod to check
oc new-project mto-test
oc create -f - <<EOF
apiVersion: apps/v1
kind: Deployment
metadata:
  name: test-deployment
spec:
  selector:
    matchLabels:
      app: hello-openshift
  replicas: 1
  template:
    metadata:
      labels:
        app: hello-openshift
    spec:
      containers:
      - name: hello-openshift
        image: gcr.io/google_containers/redis:v1

    PPO set node affinity for arch info in pod

   the mirror image is unreachable, it's a fake image, and  NeverContactSource is enabled, so PPO should not set node affinity.
