    Description

      The new NN webUI lists live node at the top of the page, followed by dead node and decommissioning node. From admins point of view:

      1. Decommissioning nodes and dead nodes are more interesting. It is better to move decommissioning nodes to the top of the page, followed by dead nodes and decommissioning nodes.
      2. To find decommissioning nodes or dead nodes, the whole page that includes all nodes needs to be loaded. That could take some time for big clusters.

      The legacy web UI filters out the type of nodes dynamically. That seems to work well.
