How do I manage state and backends for Upgrades in Kubernetes in Chef?

    # Example Chef Recipe for Managing Kubernetes State
    
    # Define the Kubernetes cluster
    kubernetes_cluster 'my-cluster' do
      action :create
      backend 'etcd'
    end
    
    # Upgrade the Kubernetes version
    kubernetes_upgrade 'my-cluster' do
      version '1.21.0'
      action :upgrade
    end
    
    # Ensure the state is maintained
    kubernetes_state 'my-cluster' do
      nodes [
        { name: 'node1', role: 'worker' },
        { name: 'node2', role: 'worker' },
      ]
      action :apply
    end
