Rename a Sidekiq Job

Official Wiki: How do I safely rename Sidekiq Worker

Say we have a OldJob wants to rename to NewJob.

class OldJob
end

Ship two PRs.

1st PR rename to NewJob and all references of OldJob and keep an name alias:

class NewJob
end

OldJob = NewJob

After all OldJob completed. Open a second PR to remove the OldJob = NewJob assignment.
