If `values.yaml` is changed, be sure to update corresponding values changes in [../profiles/default.yaml](../profiles/default.yaml)

## Step 3. Update istioctl schema

Istioctl uses a [schema](../../operator/pkg/apis/istio/v1alpha1/values_types.proto) to validate the values. Any changes to
the schema must be added here, otherwise istioctl users will see errors.

  // lastTransitionTime is the time the condition last transitioned from one status to another.
  // If unset, when a new condition type is added or an existing condition's status is changed,
  // the server defaults this to the current time.

  optional k8s.io.apimachinery.pkg.apis.meta.v1.Time lastTransitionTime = 5;
