Kubernetes API Server count flag is statically set to 3

[galexrt]

As we talked today here is the issue 😄

hetzner-kube/pkg/clustermanager/cluster.go

Lines 386 to 392 in add8676

	// set apiserver-count to 3
	for _, node := range masterNodes {
	manager.eventService.AddEvent(node.Name, "set api-server count")
	manager.nodeCommunicator.TransformFileOverNode(node, node, "/etc/kubernetes/manifests/kube-apiserver.yaml", func(in string) string {
	return strings.Replace(in, "image: gcr.io/", "- --apiserver-count=3\n image: gcr.io/", 1)
	})
	}

I have an old patch ready which I'm happy to update to latest and create a PR for.
