Back-end: create storage model and expose in Exp. Mgr.

Storage model

In resource bundles below a new node at

/hippo:configuration/hippo:translations/hippo:hst/components/ 

 then a path mimicking the fully qualified class name of the component, and a subnode for the locale (comparable with the componentparameters sibling node):

   .../com/example/components/BannerComponent/en/documentation.link

Expose to the Experience Manager

Add a documentationLink attribute to the XHR call for the component parameters:

/_rp/<component-id>./hippo-default/<locale>

to retrieve properties for container items.

This is backed by model class org.hippoecm.hst.pagecomposer.jaxrs.model.ContainerItemComponentRepresentation instantiated by XPageContainerItemComponentServiceImpl and ContainerItemComponentServiceImpl
