the api version: `keda.sh/v1alpha1` is not found on OCP version 4.16 and 4.17. When we attempt to apply a scaledObject resource and a trigerredAuthentication resource with this kind, within the ingressController, there is an error. 

    OCP-4.16 and OCP-4.17

    Always

    1. Navigate to ingress operator, 'autoscaling an ingress operator' section: https://docs.openshift.com/container-platform/4.16/networking/ingress-operator.html#nw-autoscaling-ingress-controller_configuring-ingress
    2. Start from step 1, attempt to apply triggerAuthentication YAML (step 3B) 
    3. Notice there are no matches for triggerAuth with keda api version
    4. Attempt step 6, similar issue with no matches for scaledObject on keda apiVersion

ensure CRDs are installed first

scaledObject and triggerAuthentication should be applied successfully in apiVersion
