Kubernetes 1.22 support and 1.24 upgrade

[spillee]

Since AWS EKS support for Kubernetes 1.21 ends on Feb 15, 2023, wonder if Cloudforet supports K8s 1.22 and/or above versions.

• AWS EKS release calendar and support plan

Target Kubernetes version to upgrade: 1.24

Issues to be investigated;

• AWS EKS update guide
• Kubernetes version 1.22 prerequisites
• Kubernetes API and Feature Removals In 1.22
• Kubernetes 1.22 deprecation guide
• EKS 1.23 changes
• EKS 1.24 changes
• Removing Dockershim

I need verification if Cloudforet supports K8s 1.24 and can be upgraded without issue by end of Janurary since current 1.21 support ends on Feb 15.
