We need to verify this feature works as intended.

Steps seem to install the latest QE build seem to be in this card: https://issues.redhat.com/browse/AUTOSCALE-303

mburke@redhat.com has written a draft for documentation of this feature. 

I think the simplest way we can check this on OCP is going through this draft guide in Michael's PR: https://96335--ocpdocs-pr.netlify.app/openshift-enterprise/latest/nodes/cma/nodes-cma-autoscaling-custom-trigger#nodes-cma-autoscaling-custom-prometheus-config_nodes-cma-autoscaling-custom-trigger

Although, I'm not sure if there is one step that is missing (adding rbac to the keda-operator such that it can request service account tokens).

Dod: feature is fully working as intended as spelled out in the draft documentation.
