Scaling issues with cks cluster

### problem

Scaling issues with cks cluster

### versions

ACS 4.23, 4.22
Hypervisor : KVM
CKS : 1.36

### The steps to reproduce the bug

Steps to reproduce the issue

1. Create 2 service offerings

2. create kubernetescluster name=cks-npe zoneid=157cb8ca-1c40-4a1f-a737-8bddb1dcb2fd kubernetesversionid=e8d2b996-54c8-457a-9a54-985ebc46b332 networkid=f2d97bea-3e96-44bd-ae16-fd98d7ea8a8e controlnodes=1 size=2 nodeofferings[0].node=control nodeofferings[0].offering=bf332776-e6c1-43cb-922d-7de6bb5d38a7 nodeofferings[1].node=worker nodeofferings[1].offering=d7892a54-8604-44ab-8892-dcd1357571a0 hypervisor=KVM

Check the database

```
mysql> SELECT name, state, service_offering_id, control_node_service_offering_id, worker_node_service_offering_id, etcd_node_service_offering_id, etcd_node_count FROM cloud.kubernetes_cluster WHERE name='cks-npe' AND removed IS NULL;

### What to do about it?

Scaling should work without any exception message

Commencez par ScaleKubernetesClusterCmd et KubernetesClusterScaleWorker, en utilisant les étapes de reproduction et les erreurs du management-server comme guide initial. Suivez la manière dont les offres de service sont sélectionnées pour les nœuds de contrôle, worker et ETCD. C'est terminé lorsque les demandes de mise à l'échelle du cluster présentées n'échouent plus à cause d'une offre de service null ou d'une offre ETCD manquante.

Rédigé par le modèle d'indexation à partir du texte de l'issue.
