Unable to auto-scale Kubernetes cluster

Hi!

I am unable to auto-scale Kubernetes clusters. As I understand, it create a "cluster-autoscaler" deployment that decides whether to scale or not. However, it does not seem to work, since it logs multiple errors and warnings in the pod, even though it is a completely clean cluster.

Normal scaling seems to work just fine.

# Setup
A "default" CloudStack setup **4.18** running KVMs.

## Settings (relevant)
- Cloud kubernetes service enabled **true**
- Cloud kubernetes cluster experimental features enabled **true**
- Cloud kubernetes cluster max size **50**

The nodes uses the following service offering:
- 2 CPU x 2.05 Ghz
- 2048 MB memory
- 8 GB root disk

# Replicate
1. Create a new cluster using Kubernets 1.24 ISO found here:
http://download.cloudstack.org/cks/

2. Enable forced auto-scaling
Since the cluster starts with only one worker node, auto-scaling with 3-5 nodes should trigger an upscale (I assume)

4. Check the logs for cluster-autoscaler in the Kubernetes cluster
Some notable entries:
```

```
Even though I have not edited anything myself (just a clean CKS cluster), I get these weird logs:

```

I0807 14:57:06.667061 1 static_autoscaler.go:341] 2 unregistered nodes present
```
The IDs are correct in CloudStack

The entire log:
[logs-from-cluster-autoscaler-in-cluster-autoscaler-5bf887ddd8-hxg2g.log](https://github.com/apache/cloudstack-kubernetes-provider/files/12281530/logs-from-cluster-autoscaler-in-cluster-autoscaler-5bf887ddd8-hxg2g.log)

Please tell me if you need more logs to look at, or if I should try some other configuration.

Thanks!

Riproduci il problema con la configurazione CloudStack 4.18, l’ISO Kubernetes 1.24 e il deployment di cluster-autoscaler descritti nell’issue. Inizia esaminando i log dei pod di cluster-autoscaler, in particolare gli avvisi RBAC e unregistered-node. Il lavoro sarà completato quando sarà identificata la causa e sarà ripristinato l’autoscaling previsto senza gli errori segnalati.

Scritto dal modello di indicizzazione a partire dal testo della issue.
