/**
 * Base destination class for importing configuration entities.
 *
 * Available configuration keys:
 * - translations: (optional) Boolean, if TRUE, the destination will be
 *   associated with the langcode provided by the source plugin. Defaults to
 *   FALSE.
 *
 * Examples:
 *
 * @code
 * source:
 *   plugin: d7_block_custom
 * process:
 *   id: bid
 *   info: info
 *   langcode: language
 *   body: body
 * destination:
 *   plugin: entity:block
 * @endcode
 *
 * This will save the migrated, processed row as a block config entity.
 *
 * @code
 * source:
 *   plugin: d6_profile_field_translation
 *   constants:
 *     entity_type: user
 *     bundle: user
 * process:
 *   langcode: language
 *   entity_type: 'constants/entity_type'
 *   bundle: 'constants/bundle'
 *   field_name: name
 *   ...
 *   property: property
 *   translation: translation
 * destination:
 *   plugin: entity:field_config
 *   translations: true
 * @endcode
 *
 * Because the translations configuration is set to "true", this will save the
 * migrated, processed row to a "field_config" entity associated with the
 * designated langcode. Note that the this makes the "translation" and
 * "property" properties required.
