hetzner: improve Cluster Autoscaler integration The Cluster Autoscaler Hetzner provider keys node group membership, initial target size and Nodes() entirely off the hcloud/node-group server label, which kOps never set. As a result kOps-created servers were invisible to the autoscaler. - Label Node-role servers with hcloud/node-group at creation. Servers from earlier kOps versions get the label when they are replaced. - Treat minSize as a floor: servers beyond Count are no longer marked needs-update, so autoscaler scale-ups survive kops update cluster. Shrink with 'kops delete instance' or autoscaler scale-down. Signed-off-by: Ciprian Hacman <ciprian@hakman.dev>
