What would you like to be improved?

In K8S operator, we use autoscaling/v2beta2, in K8S 1.24, they remove autoscaling/v2beta2, they have autoscaling/v2.

How should we improve?

We should adapt to 1.24. I don't know whether we can adapt to the old versions.

@advancedxy @wangao1236 Could you give me some input?

I have a solution. https://github.com/VictoriaMetrics/operator/blob/master/controllers/factory/k8stools/version.go

1.24 is already end of life^1. I think the master code should target the latest K8S version instead.

However there might be some pretty old k8s clusters runnings in the prod. @wangao1236 do you have any idea about the backward compatibility of K8S versions? Is it safe for operator to depends on a newer version of k8s and deploys to an old one with limited usage of new APIs.
