forward_service is nondescriptive and misnamed, as it does more than forward requests. It's a classic map/reduce algorithm (and in fact one of its parameters is "reducer"), so name it accordingly. The name "forward" leaked into the wire protocol for the messaging service RPC isolation cookie, so it's kept there. It's also maintained in the name of the logger (for "nodetool setlogginglevel") for compatibility with tests. Closes scylladb/scylladb#19444
