created manifests can be done through overlays.
1. [CLI](#cli) code. CLI code shares the `IstioOperatorSpec` API with
the controller, but allows manifests to be generated and optionally applied from the command line without the need to
run a privileged controller in the cluster.
1. [Migration tools](#migration-tools). The migration tools are intended to
automate configuration migration from Helm to the operator.
