Post auction event listener is now properly initialized for the augmentor example.

Note that there's a bug in ZmqMultipleNamedSubscriber where it can't
be added as a source for another message thread. For the moment the
augmentor will run on two threads (which is a good idea anyhow).
Fixed various small issues with the rtbkit integration test.

These includes:
- monitor initialization now includes the agent config service.
- agents are now setup properly.
- agent configuration will now be applied properly.
MonitorEndpoint now has a custom bindTcp function which fetches its port from service proxy.
Fixed the mock exchange and ad server port selection for rtbkit integration test.
