Once topology goes GA, let's update the default storageclasses to set "WaitForFirstConsumer" volume binding mode. The addon is set to "EnsureExists", which means that if the object is already created, then we do not modify it. So users upgrading will not be affected. Only new clusters created will get the new default storageclass. This will need an "ACTION REQUIRED" release note that users need to update their workflow if they were dependent on the PVC being provisioned first before creating Pods.
