UI review ticket: Scopes not displayed for servers in standby mode

The user tried to look at the scopes held by each member of the HA pair. This information wasn't available. He also seemed to think that HA was not configured correctly because the standby machine reported it was not serving any scopes. I think that is as designed.

Please a tip in the HA display to say that if the server is not presently active, no scopes will be shown. If that won't fit on screen, then we could alternatively just mention that in the documentation.
