Manifest rendering is a multi-step process, shown in the figure below. ![rendering
process](images/operator_render_flow.svg) The example in the figure shows the rendering being triggered by a CLI `mesh`
command with a `IstioOperatorSpec` CR passed to it from a file; however, the same rendering steps would occur when an
