Update deprecated v1beta1.PodDisruptionBudget to v1.PodDisruptionBudget

[szelenka]

Expected behaviour

Add PodDisruptionBudget in k8s past version 1.25

Actual behaviour

Operator code explicitly references v1beta1.PodDisruptionBudget which is deprecated. This should be updated to v1.PodDistributionBudget
https://pkg.go.dev/k8s.io/[email protected]/policy/v1#PodDisruptionBudget

Steps to reproduce the behaviour

Install operator on k8s 1.21+ and create a Redis cluster through the Operator, view the Operator logs

Environment

How are the pieces configured?

• Redis Operator version - v1.1.1
• Kubernetes version - 1.21
• Kubernetes configuration used (eg: Is RBAC active?) - yes
