Add Retry Option

Hi @didil,

I fixed all the merge conflicts from #4 and followed what @Saicheg did with the changed default options

To review, this is a feature to add a retry option to the cli:

-retry false or -r false - Tells Sidekiq to not retry the job, if the job fails
-retry 5 or -r 5 - Tells Sidekiq to retry the job at most 5 times, if the job fails

This mimics the options of sidekiq's advanced options (https://github.com/mperham/sidekiq/wiki/Advanced-Options#workers)

I paired with @unicornzero on the merge conflict from my previous PR #4
