> Currently, our testing infrastructure does not have a mechanism of 
> filtering/dropping HTTP events of a particular type from the Scheduler API 
> response stream.  We need a {{DROP_HTTP_CALLS}} abstraction that can help us 
> to filter a particular event type.
> {code}
> // Enqueues all received events into a libprocess queue.
> ACTION_P(Enqueue, queue)
> {
>   std::queue<Event> events = arg0;
>   while (!events.empty()) {
>     // Note that we currently drop HEARTBEATs because most of these tests
>     // are not designed to deal with heartbeats.
>     // TODO(vinod): Implement DROP_HTTP_CALLS that can filter heartbeats.
>     if (events.front().type() == Event::HEARTBEAT) {
>       VLOG(1) << "Ignoring HEARTBEAT event";
>     } else {
>       queue->put(events.front());
>     }
>     events.pop();
>   }
> }
> {code}
> This helper code is duplicated in at least two places currently, Scheduler 
> Library/Maintenance Primitives tests. 
> - The solution can be as trivial as moving this helper function to a common 
> test-header.
> - Implement a {{DROP_HTTP_CALLS}} similar to what we do for other protobufs 
> via {{DROP_CALLS}}.
