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.
Prevent exit of node bidding agent
expose queue size in the logger
replace tabs by spaces
The augmenter example now properly parses the UserIds string when receiving a win notification.
