Description
Whenever new keys are added to the NM state store it will break rolling downgrades because the code will throw if it encounters an unrecognized key. If instead it skipped unrecognized keys it could be simpler to continue supporting rolling downgrades. We need to define the semantics of unrecognized keys when containers and apps are cleaned up, e.g.: we may want to delete all keys underneath an app or container directory when it is being removed from the state store to prevent leaking unrecognized keys.
