-// GetTieredStoreInfo gets TieredStoreInfo from RuntimeInfo, the TieredStoreInfo is converted from datav1alpha1.TieredStore and stored in RuntimeInfo when building RuntimeInfo, so it can be used directly without conversion when getting it from RuntimeInfo.
-// The conversion logic is in WithTieredStore function.
-// If the length of Levels in datav1alpha1.TieredStore is 0, the Levels in TieredStoreInfo will also be an empty slice.
