typeKeyForModel(model) {
    return dasherize(this._container.inflector.pluralize(model.modelName));
  }
Used to customize the `type` field of the document. By default, pluralizes and dasherizes the model's `modelName`.

    For example, the JSON:API document for a `blogPost` model would be:

    ```js
    {
      data: {
        id: 1,
        type: 'blog-posts'
      }
    }
    ```

    @param {Model} model
    @return {String}
