Description: 

Creating a new \Drupal\elasticsearch_connector\Event\QueryParamsEvent now requires a new query parameter.

A 3rd parameter has been added to contain the \Drupal\search_api\Query\QueryInterface that is being built when the event is dispatched.

Before

new \Drupal\elasticsearch_connector\Event\QueryParamsEvent(
  $indexName, // a string
  $params, // an array
);

After

new \Drupal\elasticsearch_connector\Event\QueryParamsEvent(
  $indexName, // a string
  $params, // an array
  $query, // a \Drupal\search_api\Query\QueryInterface
);
