1. Add List dispaly Params 'brand' and List filter Params 'brand' for GuestTemplate and ScalingGroup. 2. ScalingActivity's list elem should be sorted in order by StartTime and EndTime 3. HealthCheckCycle and HealthCheckGov in ScalingGroup work now 4. Detach all ScalingGroup when pending delete Guest 5. If the scaling behavior of the scaling group fails n(n is 3 for now) times consecutively, the controller will automatically disablet this group 6. Timer will trigger ScalingPolicy throught request but func call
