Luca Cavanna 6eaff9432d SearchTemplateRequest to implement CompositeIndicesRequest (#21865)
SearchTemplateRequest to implement CompositeIndicesRequest

Given that SearchTemplateRequest effectively delegates to search when a search is being executed, it should implement the CompositeIndicesRequest interface. The subrequests method should return a single search request. When a search is not going to be executed, because we are in simulate mode, there are no inner requests, and there are no corresponding indices to that request either.
