As an Admincentral user, I want to see a value in the linkfield that I can understand, so that I know what external content is linked.

As a Developer, I want to easily provide a preview for a linked external content item.

Currently authors by default see the ID of the remote content item, which can be a UUID or something else that is not helpful. It should be easy for a developer to configure a property from the external content (REST client) to be used for the preview.

Example:

Example - my app lets me link to git commits. The hash is stored as the link in JCR, but the author wants to see the commit message.

Chooser shows messages:

But afterwards the field shows the hash (which is what is stored in JCR.) It should show the Message.**
