Today, the Kiali CRD has no real schema. This epic is to introduce a CRD Schema to the Kiali CRD.

Today, a user can currently create a Kiali CR with invalid fields or fields in the wrong place or fields of the wrong type etc. There is no validation at create time to give you an error when this happens. in order to validate the CR the user must manually run the validation script that is provided by the Kiali team - see https://kiali.io/docs/configuration/kialis.kiali.io/#validating-your-kiali-cr
