Debug: print mqttClient error code when connection fails

[pennam]

It can provide useful feedback on why connection fails:

#define MQTT_CONNECTION_REFUSED            -2
#define MQTT_CONNECTION_TIMEOUT            -1
#define MQTT_SUCCESS                        0
#define MQTT_UNACCEPTABLE_PROTOCOL_VERSION  1
#define MQTT_IDENTIFIER_REJECTED            2
#define MQTT_SERVER_UNAVAILABLE             3
#define MQTT_BAD_USER_NAME_OR_PASSWORD      4
#define MQTT_NOT_AUTHORIZED                 5
