Developer Curb Appeal: Cloud Admin UI: Need legend, and maybe mouse-over

It's nice that we display a cloud view showing a graphical representation of the cluster.

However, it'd be nice if we included a Legend to explain what the colors mean.

Some reasons the current system might not be as obvious as you'd think:

• The colors don't look exactly Green, Yellow, Red, and Gray on some monitors
• I'm told that the green=good, red=bad, etc isn't universal in all countries.
• Some people can't see the colors. Of course a color code legend won't be of much help to a color blind person. Ideally we might also put a textual status in parenthesis to the right of the IP address.

Additionally it'd be nice to have some type of mouse-over with a bit more summary info, if known. (although that doesn't help tablet users).

We could consider changing the click behavior to show the mouse-over dialog box, and then let them click in there to open a new window with that other node's details.

It would also be nice to indicate which node we're currently on.
