Adjusted raft-autopilot to respect the minimum quorum setting regardless of what type of server it's dealing with (stale, failed, voters, non-voters).
Servers will be allowed to be removed in order of increasing precedence until the threshold is reached (stale-non-voters => stale=> voters, failed-non-voters => failed-voters).
The following has been added to the Promoter interface: PotentialVoterPredicate(NodeType) bool. This is to allow the application to make decisions about which types of node can be voters, as they may have added additional types to NodeType.
Finally, we should note that any downstream integrators of this repo may have work to do when moving to a new version due to the addition to the interface, however at the time of creation there were only HashiCorp repos consuming this and 2 external repos (https://pkg.go.dev/github.com/hashicorp/raft-autopilot?tab=importedby).
