In this release changes have been made to ensure that autopilot respects the configured minimum quorum when deciding which stale or failed servers to remove from the raft configuration.
In order support this change, the promoter interface has been modified to add an additional method (IsPotentialVoter).
This allows raft-autopilot to delegate the decision making on whether a particular node type could be a potential voter in the future (as node types are extendable within consuming client code).
