gordon chung 24503c3987 reset listeners on agent refresh
each time an agent joins/leaves group, we kill and refresh the list
of pipeline listeners each agent has. this list previously did not
clear the killed listeners so the list of listeners of an agent
would grow with a bunch of dead listeners. this patch removes
references to the dead listeners.
