protected function NodeCloneFormController::getFormObject in Node clone 8

Instead of a class name or service ID, $form_arg will be a string representing the entity and operation being performed. Consider the following route:

  path: '/foo/{node}/bar'
  defaults:
    _entity_form: 'node.edit'

This means that the edit form for the node entity will used. If the entity type has a default form, only the name of the entity {param} needs to be passed:

  path: '/foo/{node}/baz'
  defaults:
    _entity_form: 'node'
