As an extension developer I want to reset the weighted_tags field managed by CirrusSearch so that I can update the index without relying on regular page updates.
AC:
- rename ores_articletopics to weitghted_tags in the mapping configuration
- the weighted_tags field should be used with the multilist noop handler during updates
- a public function CirrusSearch::resetWeightedTag( $pageId, $tagCategory ) is available to reset the tag synchronously (using an ElasticaWrite job)
