def delete_from_chef(server_name)
  # delete the node from Chef if purge requested.
  if config[:purge]
    thing_to_delete = config[:chef_node_name] || server_name
    destroy_item(Chef::Node, thing_to_delete, "node")
    destroy_item(Chef::ApiClient, thing_to_delete, "client")
  else
    ui.warn("Corresponding node and client for the #{server_name} server were not deleted and remain registered with the Chef Server")
  end
end

#destroy_item(klass, name, type_name) ⇒ Object

Extracted from Chef::Knife.delete_object, because it has a confirmation step built in… By specifying the ‘–purge’ flag (and also explicitly confirming the server destruction!) the user is already making their intent known. It is not necessary to make them confirm two more times.
