>
> * Introduce 2 new phases of upgrade action hooks (per layout feature)
> *Prefinalized state validation* - A layout feature (version) can use this to
> validate that the component is not started up in a way to use it before
> finalization. For example, an SCM HA validation action can make sure HA is
> not enabled before finalization.
> *First Upgrade Start action* - Run exactly once when a component is started
> up after an upgrade with an unfinalized layout feature.
> * Annotation based registration of layout actions to the layout features.
> After this change, an HDDS upgrade action be created like this.
