WIP: #17467 Included the possibility of a permissions issue in 404 error messages
requested to merge lbennett/gitlab-ce:17467-Add-a-message-to-the-404-page-to-indicate-it-may-be-a-permission-issue into master
What does this MR do?
- Adds the possibility of a permissions issue to the 404 error message, as well as its accompanied solution suggestion.
- Allows 404 page layout to be responsive.
Are there points in the code the reviewer needs to double check?
Should the other statically served error pages be responsive?
Why was this MR needed?
Users with incorrect permissions should not just be told the resource could not be found but also malicious users should not know exactly when and where they need elevated permissions.
What are the relevant issue numbers?
Fixes #17467 (moved).
