NorskManager.addClusterMember() method
Add a member at run time: a Manager whose node name no config.yaml names. The cluster records that it expects node; the node joins when its Manager starts with the existing members in its own clusterNodes. Idempotent; forwarded to the primary. Returns every member the cluster now expects.
Signature:
addClusterMember(node: string, by: string): Promise<{
configured: string[];
}>;
