Passing a configuration object/struct that contains multiple attributes

Here, we pass the ClientConfig configuration data object and print its values out:

func printClientConfig(config *ClientConfig) {   Info.Printf(" - security params: %v", config.SecurityParams)   Info.Printf(" - core limit: %v", config.CoreLimit)   Info.Printf(" - payload config: %v", config.PayloadConfig)   Info.Printf(" - channel number: %v", config.ClientChannels)   Info.Printf(" - load params: %v", config.LoadParams)   // . . .
