User Story

As a devfile registry admin I want to update my existing deployment so it can run either headless or non-headless

Currently, when a DevfileRegistry is deployed and a patch update is made changing the headless boolean from true to false, I expect an additional pod for the registry-viewer to be created but the update does not get triggered because we do not handle that configuration: https://github.com/devfile/registry-operator/blob/main/controllers/update.go

cat <<EOF | oc apply -n test -f -
apiVersion: registry.devfile.io/v1alpha1
kind: DevfileRegistry
metadata:
  name: devfile-registry-test
spec:
  tls:
    enabled: false
  devfileIndexImage: quay.io/devfile/devfile-index:next
  headless: true
EOF

Acceptance Criteria

• Updates should be supported when headless is toggled between true and false
• Unit/Controller tests are added
• Documentation for DevfileRegistry CRD updated
