Drupal8: when visiting a live page, make sure that non-ready pages redirect back to d7
We are going to start directing traffic of specific pages to the new Drupal8 site. However, as per the plan, pages such as blog posts, extensions, user logins, will continue to be on d7 until the new site is completely ready.
This issue is to track configurations required so that users are transparently directed from one site to the other.
