Goal

• The goal of this epic is to refactor the Karpenter operator and Karpenter deployments to use the CPOv2 architecture introduced here  https://github.com/openshift/hypershift/tree/main/support/controlplane-component

Why is this important?

• This is a necessary step to remove all references to the legacy DeploymentConfig code which is used today for Karpetner operator. related: https://issues.redhat.com//browse/CNTRLPLANE-844

Scenarios

Acceptance Criteria
