Example events from the ScaledObject

Normal  KEDAScalersStarted          21m                keda-operator  Started scalers watch
Normal  KEDAScaleTargetDeactivated  21m                keda-operator  Deactivated apps/v1.Deployment demo-keda/httpbin from 1 to 0
Normal  ScaledObjectReady           20m (x2 over 21m)  keda-operator  ScaledObject is ready for scaling

After publishing 200 messages to the queue, the httpbin deployment scaled up.
