Increase visibility of the security reports in the merge request
Problem to solve
Security reports in the MR widget are great, and so the security dashboards.
Unfortunately they may be entirely missed even if there, and this makes them totally useless.
We should improve visibility of security reports.
Further details
This is happening also to us, see for example https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/23378#note_120416570
Proposal
Make security more visible, specifically when there is something to warn about.
