ScaledObject created with transfer-hpa-ownership annotation does not set .status.hpaName

[SriRamanujam]

Report

When creating a ScaledObject with the scaledobject.keda.sh/transfer-hpa-ownership annotation, it does not set .status.hpaName.

Expected Behavior

Adopted/transferred-ownership ScaledObject resources should have .status.hpaName set to the name of the HPA referenced in .spec.advanced.horizontalPodAutoscalerConfig.name

Actual Behavior

.status.hpaName is unset in all cases except when KEDA was responsible for the initial creation of the managed HPA.

Steps to Reproduce the Problem

1. Create an HPA.
2. Create a ScaledObject with the transfer-hpa-ownership annotation combined with .spec.advanced to have KEDA take over the HPA.
3. Observe that .status.hpaName never gets set on the ScaledObject.

Anything else?

I think that this may be an issue for any ScaledObject where the first reconcile loop doesn't go through this block, tracing through the code this seems to be the only place where status.HpaName is set and it's only called when HPAs are initially created.

Are you willing to fix this bug? :)

@SpiritZhou I'm happy to take a crack at it, but I wanted to confirm that this is in fact a bug and not intended behavior or otherwise load-bearing :D

[SpiritZhou]

I believe this is a bug. but we can ask @zroubalik @JorTurFer @wozniakjan to double check

It looks as a bug, yeah
