Document who should be assigned regular MRs that target stable branches
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/24870 targets a stable branch directly, and is not security related. To the best of my knowledge we don't have any clear guidelines on who to assign such MRs to. For MRs targeting master
this doesn't matter, but I think in this case they should be assigned to a release manager for extra visibility.
