The propagated conditions are visible via crictl info, but not visible via kubectl get nodes -o yaml yet, although the CRI API says "These conditions will be exposed to users to help them understand the status of the system".

Specifically for the deprecation messages, this may confuse some customers. In GKE, for example, we set mirrors using "old way" because there are customers who are adding other mirrors this way. So we have a separate detection mechanism that will tell those customers that the change is needed and we will switch the config mode when we are sure that it will not break those customers customizing things manually.

If this will be exposed widely, we may need to have some mechanism to hide certain deprecation warnings than.

cri: propagate deprecation list to runtime status

Propagate the deprecation list to CRI runtime conditions.

The propagated conditions are visible via `crictl info`,
but not visible via `kubectl get nodes -o yaml` yet, although
the CRI API says "These conditions will be exposed to users to help
them understand the status of the system".
