podSecurityPolicy has been removed

[blevz]

What happened: Rbac-tool fails to build for modern k8s versions bc pod security policy has been deprecated and removed from the k8s library

What you expected to happen: Rbac-tool compiles when using support k8s library version

How to reproduce it (as minimally and precisely as possible): Upgrade k8s client to v 1.28 and try to build

Anything else we need to know?:

Environment:

• Kubernetes version (use kubectl version):
• Cloud provider or configuration:
• Install tools:
• Others:

@blevz - thanks - final removal will take place once dependencies are updated to a later k8s version
