Signed-off-by: Zbynek Roubalik zroubali@redhat.com

Adding Conditions to the ScaledObject(and potentially ScaledJob) Status. It's kubernetes standard way how to inform users. Adding 2 conditions:

• Ready this is set to True if ScaledObject is correctly specified and able to get metrics
• Active informs user whether scaling is active, not active or whether cooldown is happennig

Here you can see snippets of ScaledObject output:

$ oc get scaledobject test-scaledobject
NAME                 SCALETARGETKIND      SCALETARGETNAME   TRIGGERS      READY   ACTIVE    AGE
test-scaledobject   apps/v1.Deployment   test-keda        azure-queue      True    False   22s

$ oc get scaledobject test-scaledobject -oyaml
...
status:
  conditions:
  - message: ScaledObject is defined correctly and is ready for scaling
    reason: ScaledObjectReady
    status: "True"
    type: Ready
  - message: Scaler cooling down because triggers are not active
    reason: ScalerCooldown
    status: "False"
    type: Active
