Christian Decker b359a24772 cln-plugin: Handle --help invocations better ... We now have ternary outcomes for `Builder.configure()` and `Builder.start()`: - Ok(Some(p)) means we were configured correctly, and can continue with our work normally - Ok(None) means that `lightningd` was invoked with `--help`, we weren't configured (which is not an error since the `lightningd` just implicitly told us to shut down) and user code should clean up and exit as well - Err(e) something went wrong, user code may report an error and exit.		2022-04-11 15:20:32 +09:30
