Review Comment:
I think we don't need all code related to the augmentation map in the
CausalityDataNodesEngine#dataNodes method. This code is needed for zones with
immediate timers. But now the initDataNodesAndTriggerKeysInMetaStorage() watch
listener updates augmentation and returns the future which is completed when
the data nodes is updated in MS. So we don't need to add/remove nodes from the
augmentation map to data nodes from MS.
