Do not trigger CI build from specific users

I have a web hook that updates the Changelog when issue status changes. Changelog is generated from Gitlab API and is pushed to the repository by a dedicated user that's only job is to do this push. I want the CI builds to be disabled for this user, because when I push a new code from a human user, builds is triggered twice - first after my commit, second - after commit with a new changelog.

I propose to make a setting for project builds or build runners that would allow to blacklist specific users from triggering the builds.
