Creates a key value collection for migrated node translation redirections.
If we are migrating node translations from Drupal 6 or 7, these nodes will be combined with their source node. Since there still might be references to the URLs of these now consolidated nodes, this service saves the mapping between the old nids to the new ones to be able to redirect them to the right node in the right language.
The mapping is stored in the "node_translation_redirect" key/value collection and the redirection is made by the NodeTranslationExceptionSubscriber class.
