Allow user to disable all Auto DevOps banners
It was raised in that issue that having auto-devops banner is annoying as you have to disable it for every single repo: https://gitlab.com/gitlab-org/gitlab-ce/issues/38472.
We have an administrative way to disable that feature, but we didn't built a per-user thing for that: https://docs.gitlab.com/ce/topics/autodevops/#disable-the-banner-instance-wide.
This issue is to reconsider adding that on per-user without having the administrator to make a change.
