> Based on the discussion with Wangda Tan, current implementation of Queue is not easy
to use if number of nodes is large, and visualization is not very straightforward in terms
of node hierarchy and details. Therefore, we want to refactor queue visualization to be more
user friendly for different use cases.
> The image above is the mockup for the new queue visualization, basically it should have
the following features:
> 1. Each node would be visualized by a horizontal bar, and hierarchy would be distinguished
by indentation of each node. (e.g. If one node is a child node of another parent node, there
would be indentation before the child node.)
> 2. Each node would show usage info on its bar, e.g. displaying used usage like a progress
bar along with the percentage.
> 3. Click +/- to expand/collapse the tree to show/hide nodes.
> 4. Click on bar would show detail charts on the bottom.
> 5. A filter on the top-right would filter the nodes based on options. 
> Currently I finished feature 1 and feature 2. See screenshot. 
> Since this ticket is relatively big and would take a while to complete, I will keep the
ticket updated. Don't hesitate to comment your idea or suggestion. Thanks!
