change the to use kubelet_extra_args for bottlerocket

[liyihuang]

this is the PR so we can use kubelet_extra_args for bottlerocket

module "eks" {
  source = "../terraform-aws-eks"

  disable_aws_vpc_cni_plugin = true
  kubernetes_version         = var.kubernetes_version
  manage_aws_auth_configmap  = true
  name                       = local.cluster_name
  region                     = var.region
  tags                       = var.tags
  vpc_id                     = module.vpc.id

  self_managed_node_groups = {
    x86 = {
      platform                 = "bottlerocket"
      ami_name_filter          = var.x86_ami_name_filter
      extra_tags               = {}
      instance_type            = var.x86_worker_instance_type
      kubelet_extra_args       = <<-EOT
        [settings.host-containers.admin]
        enabled = true
        [settings.host-containers.control]
        enabled = true
        [settings.kubernetes.node-taints]
        "node.cilium.io/agent-not-ready" = "true:NoExecute"
      EOT
      max_nodes                = var.worker_max_nodes
      min_nodes                = var.worker_min_nodes
      name                     = "x86"
      post_bootstrap_user_data = ""
      pre_bootstrap_user_data  = ""
      root_volume_id           = "/dev/xvda"
      root_volume_size         = var.worker_root_volume_size
      root_volume_type         = "gp3"
      subnet_ids               = module.vpc.private_subnet_ids
      iam_role_additional_policies = {
        additional = "arn:aws:iam::aws:policy/AmazonSSMManagedInstanceCore"
      }
    },

Here is what I use.

I think it's better just use it this way so we dont break the exsiting kubelet_extra_args for other non-bottlerocket

Just one clarification comment.
