> 1. FSImage saver/loader need to be able to recognize INodeFileUnderConstruction, INodeFileUnderConstructionWithSnapshot,
and INodeFileUnderConstructionSnapshot.
> 2. FSImage saver/loader should be able to form the correct circular linked list for INodeFileUnderConstruction(With)Snapshot.
> 3. Add new corresponding unit tests and support file appending in TestSnapshot#testSnapshot.
