oc adm upgrade status currently renders Progressing and Failing!=False directly, instead of feeding them in through updateInsight. OTA-1154 is removing those. But Failing has useful information about the cluster-version operator's direct dependents which isn't available via ClusterOperator, MachineConfigPools, or the other resources we consume. This ticket is about adding logic to assessControlPlaneStatus to convert Failing!=False into an updateInsight, so it can be rendered via the consolidated insights-rendering pathways, and not via the one-off printout.
