Support scaling to Zero with combine of Cron and cpu/mem scaler

[vumdao]

Proposal

My scaled object

apiVersion: keda.sh/v1alpha1
kind: ScaledObject
metadata:
  name: app
spec:
  maxReplicaCount: 10
  minReplicaCount: 0
  scaleTargetRef:
    kind: Deployment
    name: app
  triggers:
    - metadata:
        desiredReplicas: "2"
        end: 0 21 * * *
        start: 30 7 * * *
        timezone: Asia/Ho_Chi_Minh
      type: cron
    - metadata:
        value: "85"
      metricType: Utilization
      type: cpu

I would like to scale my deployment to Zero but the cpu/mem scaler prevents that

Proposal from @zroubalik: we can allow scale to 0, in case there are multiple triggers not just cpu/mem and the activation will be driven by the non-cpu/mem scaler.
