Introduce feature flag to experiment with data_consistency
What does this MR do and why?
This MR introduces the load_balancing_for_ci_finished_builds_sync_worker
feature flag to experiment with data_consistency
, as per https://docs.gitlab.com/ee/development/sidekiq/worker_attributes.html#feature_flag-property.
This will allow checking if the duplicates we're seeing in ClickHouse by CiFinishedBuildsSyncWorker
are due to out-of-date replicas.
