As requested in #22120, moved the files and fixed other includes and build system. Moved files: - query.cc - query-request.hh - query-result.hh - query-result-reader.hh - query-result-set.cc - query-result-set.hh - query-result-writer.hh - query_id.hh - query_result_merger.hh Fixes: #22120 This is a cleanup, no need to backport Closes scylladb/scylladb#25105
