Queues column on Brokers tab

[ogorun]

I propose to add queue(s) names as a column on Brokers tab.

This helps with the following use case. Frequently I want to see at a glance status of workers consuming specific queue:

• are there workers listening to a specific queue
• how many of them are online
• how many of them are busy now and how many have capacities

I second this, also i would like that I could have use those queue names using /metrics endpoint (to group, same as task and worker)
