hystrix

at https://github.com/cep21/circuit/blob/v3.1.0/v3/example/main.go#L81

circuit.Config{} should be configured, like

circuit.Config{
General: circuit.GeneralConfig{
	OpenToClosedFactory: hystrix.CloserFactory(hystrix.ConfigureCloser{}),
	ClosedToOpenFactory: hystrix.OpenerFactory(hystrix.ConfigureOpener{}),
}

right?

I'm using log4j2 in my SpringBoot application, excluding logback implementation and logging with tracer doesn't work. It would be nice to support logging with log4j2 .
