[hobbit] Multiple hobbit (bbproxy and bb server) queries

The conn and ssh tests are handled by bbnet on the xymon server.  The cpu,
disks, memory, etc are run on each client system.  Personally I wouldn't
want to fool around with those.

The point of the little test script was that, with a much shorter lifetime,
those messages will show purple dots a lot quicker when the bbproxy dies.
 You'll also only get a maximum of three to start with.  All the other
purple dots will come along 25 minutes later, if nobody fixes the bbproxy.
