Add schema for CRD - Githubissues

Desired Outcome

One of the ways that the CyberArk Secretless Broker (SB) can be configured is by using a Kubernetes Custom Resource Definition (CRD) that is specifically created for SB Configuration. This method of configuration is documented here.

Currently, our documentation suggests that users should deploy these CRDs using the {{apiextensions.k8s.io/v1beta1}} Kubernetes API version. However, support for this API version has been fully removed in Kubernetes API controllers as of Kubernetes v1.22.

This means that any customers who want to use the Secretless Broker in Kubernetes clusters that are v1.22 or newer (or, correspondingly OpenShift v4.9 or newer) must create CRDs using the v1 API version, that is, apiextensions.k8s.io/v1.

However, for this v1 API version, the CRD specifications must include a structural schema as described here: https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions/#specifying-a-structural-schema

An example of a CRD manifest that contains a structural schema is here: https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions/#create-a-customresourcedefinition
