Add redis rate limiter feature for centrelized control of message handling

[regevbr]

It will be a cool feature, to allow the library user, to decide that he wants to rate-limit the handling of the messages across many microservices, instead of just using the concurrency control alone.
Example use case - a message queue to send emails with SMTP global hourly rate-limiting enforced.
We can leverage the following library for the task: https://github.com/dex4er/js-sliding-window-rate-limiter
