What changed?
Adding a PartitionedSnapshot function to the ChasmTree interface so snapshots can be made that separate user data from the cluster-local metadata. Also adds a way to recombine a the user data with the metadata to reconstruct the original tree state.
Why?
This allows for additional flexibility for replication-related work, where all the cluster-local metadata is not needed.
How did you test it?
Potential risks
Low risk, adding to interface.
