+++ This bug was initially created as a clone of Bug #2066262 +++ This https://github.com/openshift/kubernetes-autoscaler/pull/214 enabled upstream capi support in openshift 4.10 autoscaler fork which was referencing old annotations. The same is needed in 4.9 so It can be used by HyperShift when running 4.9 HostedClusters
Verified ocp clusterversion: 4.9.0-0.nightly-2022-03-29-031241 hypershift guest cluster: oc get hostedcontrolplane -n clusters-example-02 -ojsonpath='{.items[*].spec.releaseImage}' registry.ci.openshift.org/ocp/release:4.9.0-0.nightly-2022-03-29-031241 Steps: 1.
