          Prefer using `Worker.bulk_perform_async_with_contexts` and
          `Worker.bulk_perform_in_with_context` over the methods without a context
          if your worker deals with specific projects or namespaces
          The context is required to add metadata to our logs.

          If there is already a parent context that will apply to the jobs
          being scheduled, please disable this cop with a comment explaing which
          context will be applied.
