I don't know your approach to cluster reconfiguration, but I had a thought
about it lately that may be rather trivial, if I didn't oversee anything.
Cluster reconfiguration would need to be an operation that goes through the
leader and gets acknowledged by a quorum. All operations following the cluster
reconfiguration operation would need to be committed by the new quorum.
I hope this idea might help and I didn't make a fool of myself. :-)
