*All Istio Kubernetes usage should use this library and not operate on Kubernetes clients directly.*

**`kclient.Client`** is a higher level wrapper around a Kubernetes resource, and is built up of sub-parts `kclient.Reader`, `kclient.Writer`, and `kclient.Informer`.
Typically, the whole `kclient.Client` is used,though.

Functionality offered by `kclient` includes:
