 * Provides entity view mode destination plugin.

 * @see \Drupal\migrate\Plugin\migrate\destination\EntityConfigBase

 * Example:
 *
 * @code
 * source:
 *   plugin: d7_view_mode
 * process:
 *   mode: view_mode
 *   label: view_mode
 *   targetEntityType: entity_type
 * destination:
 *   plugin: entity:entity_view_mode
 * @endcode
 *
 * This will add the results of the process ("mode", "label" and
 * "targetEntityType") to an "entity_view_mode" entity.
