From the KubeVirt point of view, in order to enable the downward metrics feature, the user needs to add spec.configuration.developerConfiguration.featureGates: - DownwardMetrics. Since the feature is already on GA the feature gate needs to be removed, however, we still want to have the flexibility to enable/disable the feature. For this purpose, we need to add the spec.configuration.downwardMetrics: true/false.
Disabled by default.
