Reduce arguments to handle_cleartext_payload in PacketSpaceManager

[WesleyRosenblum]

handle_cleartext_payload currently requires 8 arguments, which is more than Clippy is happy with. We should potentially gather some of the arguments into a Struct to simplify

• there are a few more functions that take too_many parameters. search for all instances of #[allow(clippy::too_many_arguments)] and possibly create structs
