Some initial thought is:
decommissioning nodes should still show up in the active nodes list since they are still running containers.
A separate decommissioning tab to filter for those nodes would be nice, although I suppose users can also just use the jquery table to sort/search for
nodes in that state from the active nodes list if it's too crowded to add yet another node
state tab (or maybe get rid of some effectively dead tabs like the reboot state tab).
