Feature request: Queue#status?

[ashkank83]

Description

As discussed on the gitter channel, it would be great to add a new function to queue which returns the status of the queue. i.e. is it "Paused", "Closed", ...

If the generic queue#status is not possible then maybe queue#isPaused which returns a boolean.

ok, we can report paused, but closed is not a queue status, rather a status of your particular instance of the queue.

This feature is really useful. I would like to now if queue is active/paused globally.
