cmk create kubernetescluster serviceofferingid issue (CKS)

### problem

When using cmk to create kubernetescluster with nodeoffering, I left out the serviceofferingid (the legacy parameter pre 4.21) which I thought was optional as it will be overwritten with nodeoffering anyway.
The CKS was created sucessfully but when I try to upgrade the kubernetes cluster, I get the error "Invalid service offering associated with Kubernetes cluster". The upgrade seems to check for serviceofferingid and require it to be present even though you can create one without serviceofferingid.

A second related issue is when I put a serviceofferingid of a 1 vcpu 1 GB ram in cmk create kubernetescluster as a way to pass the upgrade check. To my suprise, when I try to upgrade, cloudstack complains that the template does not meed minimum hardware requirement even though the template I put in to nodeoffering satisfy this requirement. So it must be using serviceofferingid to verify the hardware requirement when upgrade was triggered.

### versions

4.22.1 KVM NFS

### The steps to reproduce the bug

1. use cmk (or api) to create cks with nodeoffering ommiting serviceofferingid
2. Try to upgrade CKS
3.
...

### What to do about it?

The correct behaviour for the upgrade process is to also check for the presence of nodeoffering and use this to detect minimum hardware requirement

在 CloudStack 4.22.1 上使用 cmk 或 API 重现该问题：创建一个带有 nodeoffering 但没有 serviceofferingid 的 Kubernetes 集群，然后尝试升级。跟踪 Kubernetes 集群的升级路径，并比较 serviceofferingid 与 nodeoffering 的验证方式。完成的标准是：存在 nodeoffering 时，升级使用 nodeoffering，并正确验证其最低硬件要求。
