Auto re-direct when Unpublishing content

[loreeosullivan]

When unpublishing content (blog post, landing page, etc.), this action should trigger another action which prompts the user to add a 301 redirect.

Example: "Where should this URL redirect to once this webpage is unpublished?" 

This would be SUPER helpful for antiquated blogs and would streamline the cleanup process. There could also be a blanket redirect option for the blog tool as well - ex: "when any blog is unpublished, where should the URL auto-redirect?"
