Resolve "Misalignment of Avatar when forking project"

Closes #65204

See merge request gitlab-org/gitlab-ce!31436

This will help identify Sidekiq jobs that invoke excessive number of

within the middleware and is not directly accessible to the Sidekiq
logger. However, it is possible for the middleware to modify the job
hash to pass this data along to the logger.
