> Currently, the code implementing sending and receiving of snapshots is already there. Some scenarios need to be implemented:
>  # Node that has data restarts successfully (trivial, but should make sure that 'startup snapshot' is 'applied' correctly)
>  # Start a cluster of 3 nodes, stop one of them, add some data, provoke the lagging node to restore itself from a snapshot, start it, make sure it catches up
>  # Test that a node fed with a snapshot can act as a leader later (including installing snapshots to other nodes)
>  # Test that a node that catches up using a snapshot gets updates happening concurrently with snapshot streaming, applied in the correct order
>  # Test that, if a snapshot installation fails in the middle, the recipient node's data remains consistent
