Add reviewer roulette to this project
Problem
As a newcomer to this project it's not clear whom to ping for review.
Proposed solution
Follow steps in https://gitlab.com/gitlab-org/ruby/gems/gitlab-dangerfiles/#ci-configuration
This requires us to define reviewers/maintainers in https://about.gitlab.com/handbook/engineering/projects or use piggy-bag on gitlab-org/gitlab
reviewers.
