Docker driver cpu_hard_limit is not valid

[suikast42]

I try to set the cpu_hard_limit in nomad agent client config as shown below

plugin "docker" {
  config {
    allow_privileged = false
    # Default is false. Use hard CPU limiting instead of soft limiting
    #  By default this is false which means soft limiting is used and containers
    # are able to burst above their CPU limit when there is idle capacity.
    # For overcumsuming cpu set this value in your job->group->task->config stanza
    cpu_hard_limit = true
    disable_log_collection  = false
#    volumes {
#      enabled = true
#      selinuxlabel = "z"
#    }
    infra_image = "{{nomad_infra_image}}"
    infra_image_pull_timeout ="30m"
    extra_labels = ["job_name", "job_id", "task_group_name", "task_name", "namespace", "node_name", "node_id"]
    logging {
      type = "journald"
       config {
          labels-regex =".*"
       }
    }
    gc{
      container = true
      dangling_containers{
        enabled = true
      # period = "3m"
      # creation_grace = "5m"
      }
    }

  }
}

But nomad says that the cpu_hard_limit setting is not present.

But I can set this property in nomad job like https://github.com/hashicorp/nomad/issues/19758

@suikast42 the cpu_hard_limit configuration is a task.config field, not a plugin.config field.

I didn't realize that. Sorry. Can we make a featrure request for that ?

For my usecase that's makes more sense to have it as default = true.
