Retry parameter should not be used

[lenart]

I've spent quite some time before I figured out that because I've set a retry value in sidekiq_options(retry: 2) the throttling was not working as expected. I'd make this note in the README somewhere, because I believe it's quite important.

Can you please provide a demo of the issue? Let's make throttling work with any retry options, as they should be respected.

A warning in README meanwhile is a good too :D
