Add dangerbot rule to prevent adding new Sidekiq workers
In Restructure Sidekiq workers and ActiveJob jobs (#7947 - closed) and the corresponding MR https://gitlab.com/gitlab-org/customers-gitlab-com/-/merge_requests/8722 we agreed that we don't want to have more Sidekiq workers in our codebase thus means we need to add a Dangerbot
rule that warns when new Sidekiq
worker is added under the app/workers
. Instead, the Dangerbot
must say to add it under the app/jobs
folder as an ActiveJob
.
