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

Beginnen Sie mit dem CKS-Cluster-Bereitstellungspfad und der generierten /etc/containerd/config.toml und verwenden Sie die kubelet- und crictl-Fehler als Fehlernachweis. Reproduzieren Sie das Problem mit der Einstellung experimental-features und privaten Docker-Hub-Registry-Anmeldedaten; abgeschlossen ist die Aufgabe, wenn der Cluster den Startzustand verlässt und kubelet und containerd korrekt initialisiert werden.
