Support metadata annotations in ScaledJob template's volume claims

[dpertin]

Report

Applying metadata annotations on a volume claim template, inside ScaledJob templates returns an error.
Here's the definition of the metadata annotations:

apiVersion: keda.sh/v1alpha1
kind: ScaledJob
metadata:
  labels:
    argocd.argoproj.io/instance: xxx
  name: yyy
  namespace: zzz
spec:
(...)
        volumes:
(...)
          - ephemeral:
              volumeClaimTemplate:
                metadata:
                  annotations:
                    resize.topolvm.io/increase: 15Gi
                    resize.topolvm.io/inodes-threshold: 20%
                    resize.topolvm.io/storage_limit: 1024Gi
                    resize.topolvm.io/threshold: 30%
                    volume-type: ephemeral

Expected Behavior

This should create a volume claim with the appropriate metadata annotations

Actual Behavior

It returns the following error: ScaledJob in version "v1alpha1" cannot be handled as a ScaledJob: strict decoding error: unknown field "spec.jobTargetRef.template.spec.volumes[5].ephemeral.volumeClaimTemplate.metadata.annotations"

Steps to Reproduce the Problem

1. Create a ScaledJobs based on the definition given above
2. Run kubectl apply -f using this definition
3. This returns the error

Interesting, could this be related with this other issue that we solved some years ago? #1311

If yes, are you willing to apply the same patch to the new path to keep the current annotations :)

Hey @JorTurFer,
Thanks for pointing me this related error. I applied a patch based on the fix in this issue and it solves the problem
I have proposed a PR based on this solution #6259

Thanks for the fix! He have merged #5939, and I'd say that it will fix the current issue too. Could you double check it?
