Additionally, we often need to convert to various different client forms for different libraries we integrate with.

`kube.Client` just bundles these all in one place, so we have a single object to pass around anywhere we need Kubernetes access.
Additionally, it has a fake client variant, that does the same thing but with fake clients for use in unit tests.

[proto](https://github.com/istio/api/blob/master/operator/v1alpha1/operator.proto) and
compiled to [Go
structs](https://github.com/istio/api/blob/master/operator/v1alpha1/operator.pb.go).
`IstioOperatorSpec` has pass-through fields to the Helm values.yaml API, but these are additionally validated through
a [schema](../operator/pkg/apis/istio/v1alpha1/values_types.proto).
