Fabio Kung edad52707c save deep copies of Container in the replica store
Reuse existing structures and rely on json serialization to deep copy
Container objects.

Also consolidate all "save" operations on container.CheckpointTo, which
now both saves a serialized json to disk, and replicates state to the
ACID in-memory store.
