If you try interacting with any of the two user interfaces, they will work correctly, because the browser will be able to talk to each specific app or sub-app.

* Proper syncing and shutdown logic. Checking for when an informer has fully started can be quite tricky; `kclient` automatically handles it.

Under the `kclient` package, `clienttest` also provides similar interfaces meant for writing unit tests.

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