> It is possible to have a cluster-split restarts when persistence enabled:
> Start 1, 2, 3, 4, update data. Stop
> Start 1, 2. Update data. Stop
> Start 3, 4. Update data. Stop.
> Start 1, 2, 3, 4. Stop
> We need to make sure that the second start is not allowed. This can be done by introducing baseline topology history and topology hash generation.
