Problem Description

While implementing a simple CLI app for removing orphaned consumer groups got this message:

2018/11/15 13:46:37 Successfully initialized new client
2018/11/15 13:46:37 client/coordinator requesting coordinator for consumergroup woot from kafka:9092
2018/11/15 13:46:37 client/coordinator coordinator for consumergroup woot is #3 (10.20.5.14:9092)
2018/11/15 13:46:37 Connected to broker at 10.20.5.14:9092 (registered as #3)
&{0s map[woot:Unknown error, how did this happen? Error code = 69]}
2018/11/15 13:46:37 Closing Client

Corresponding code snippet:

	config := sarama.NewConfig()
	config.Version = sarama.V1_1_0_0
	client, err := sarama.NewClient(strings.Split(*brokerList, ","), config)
	if err != nil {
		// deal with it
	}
	defer client.Close()

	broker, err := client.Coordinator(*consumerGroupID)
	if err != nil {
		// deal with it
	}

	resp, err := broker.DeleteGroups(&sarama.DeleteGroupsRequest{Groups: []string{*consumerGroupID}})
	if err != nil {
		// deal with it
	}
	fmt.Printf("%v\n", resp)

fmt.Printf("%v\n", resp) produces the &{0s map[woot:Unknown error, how did this happen? Error code = 69]} line.
Error code 69 (GROUP_ID_NOT_FOUND ) is absent apparently.

Moreover https://kafka.apache.org/protocol#protocol_error_codes and https://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol#AGuideToTheKafkaProtocol-ErrorCodes do not match. And the latter is referred to in errors.go

The suggestion is:

1. add missing error codes
2. make the error codes and descriptions match https://kafka.apache.org/protocol#protocol_error_codes for easier mapping between sarama's output and the official docs.
