Add public/internal information about GitLab administrator on self-hosted instances
Every error page you may see on GitLab self-hosted instances contains the information to contact the GitLab administrator if the problem persists. Unfortunately, there is no way for a normal user to find out who this person is in GitLab. The fact that this problem has already occurred can be seen from this forum entry. Therefore, there should be a possibility for the administrator to provide a contact email, which can then be seen on error pages and on the help page.
