Casskop doesn't work properly on Kubernetes 1.25.x

[ajoskowski]

Bug Report

We have deployed casskop operator on Kubernetes 1.24.x. Now we want to use it on Kubernetes 1.25.x. We are not able to do it, because casskop uses "beta" APIs - example for PodDisruptionBudget

What did you expect to see? I would like to be able to use casskop on Kubernetes 1.25.x

What did you see instead? Under which circumstances?

Environment

• casskop version: 2.1.0-release

• Kubernetes version information: Azure AKS 1.25.4

Possible Solution Replace "beta" apis with stable ones

Thanks @ajoskowski for opening this issue. I wonder if there is somehow a way to be compatible with both. If we make this change then it won't run on older versions of k8s AFAIU ...

Okay it seems it's been promoted in 1.21 so I think it's safe to upgrade. @ajoskowski please create a PR
