Description

Now we have node labels in the system, but there's no a very convenient to get information like "how many active NM(s) assigned to a given label?", "how much total resource for a give label?", "For a given label, which queues can access it?", etc.

It will be better to add a node-labels page in RM web UI, users/admins can have a centralized view to see such information.
