CKS cluster doesn't come up if "cloud.kubernetes.cluster.experimental.features.enabled" setting is enabled

### problem

CKS cluster doesn't come up if "cloud.kubernetes.cluster.experimental.features.enabled" setting is enabled

### versions

ACS 4.20.1, 4.21

### The steps to reproduce the bug

1. Enable the global setting "cloud.kubernetes.cluster.experimental.features.enabled" setting

2. Launch a cks cluster, enable private registry and provide your docker hub credentials

dockerregistryurl= "https://index.docker.io/v1/"
dockerregistryusername= <>
dockerregistrypassword=<>

3. CKS cluster is struck in starting state

4. On logging into control node found the following errors

```

The file

"/etc/containerd/config.toml" is not populated correctly

### What to do about it?

Cloudstack should support private container registry

Bắt đầu với quy trình cấp phát cluster CKS và /etc/containerd/config.toml được tạo, sử dụng các lỗi của kubelet và crictl làm bằng chứng lỗi. Tái hiện với thiết lập experimental-features và thông tin xác thực registry Docker Hub riêng tư; hoàn tất khi cluster rời khỏi trạng thái khởi động và kubelet cùng containerd được khởi tạo chính xác.
