Spring ReactiveElasticsearchOperations does not have option to include request_cache path param in search request

Elastic search provides an option to add a path param to any search queries called _request_cache=true which enables it to cache any incoming queries and its results.

The SearchRequest class provides a way to add this param using the .requestCache(Boolean.TRUE) method. But the RequestFactory.java present in Spring DATA that converts a NativeSearchQuery into SearchRequest doesn't support this argument.

Thus this parameter cannot be added to any request for search using ReactiveElasticSearchOperations
