/**
 * Drupal 7 taxonomy term source from database.
 *
 * Available configuration keys:
 * - bundle: (optional) The taxonomy vocabulary (machine name) to filter terms
 *   retrieved from the source - can be a string or an array. If omitted, all
 *   terms are retrieved.
 *
 * Examples:
 *
 * @code
 * source:
 *   plugin: d7_taxonomy_term
 *   bundle: tags
 * @endcode
 *
 * In this example terms of 'tags' vocabulary are retrieved from the source
 * database.
 *
 * @code
 * source:
 *   plugin: d7_taxonomy_term
 *   bundle: [tags, forums]
 * @endcode
 *
 * In this example terms of 'tags' and 'forums' vocabularies are retrieved
 * from the source database.
 *
 * For additional configuration keys, refer to the parent classes.
 *
 * @see \Drupal\migrate\Plugin\migrate\source\SqlBase
