Add support to `check-rabbitmq-consumers.rb` for specifying the vhost

[javierjeronimo]

Our queues are in a specific vhost, so we need to provide user, password and vhost in check-rabbitmq-consumers.rb

Sorry for lack of response, from what I see it likely does not look at which vhost its on and I would need to sit down and look at rmq apis to be sure. Did you try and it fails or are you worried that there might be a conflct if someone else should add a queue with the same name on a different vhost? Some very simple trial and error would validate both cases here.

We have same problems, we have two virtualHost with same name of queue.
