PR#57800 added theQueueManager@pause() method to allow pausing a given queue.

This method pauses the queue indefinitely by using a cache's storeforever() method.

As such a queue can only be resumed by calling theQueueManager@resume() method added in the same PR.

When consuming an external API with rate limiting, one can get a429 response when the rate limit is surpassed.

Often times this response is accompanied by theRetry-After header that gives the number of seconds to wait before retrying.

Currently, one would need to keep track of those seconds to manually pause a queue (when a429 response is received) and manually resume a queue (when the timeout is expired).

This PR

• Adds theQueueManager@pauseFor() method that allows passing the number of seconds a queue should be paused.
• Fixes some test cases and adds relevant assertions to test for the presented use case.
  • It seems the original PR aimed for allowing the seconds to be passed, so there were already tests in place testing for a third$seconds argument.
