Before:- Stacktack threw an exception and was unable to log the message. It later tries to process the same erroneous notification repeatedly. After: Stacktach catched the malformed notification and logs the message. It later acknowledges RabbiMQ so that the message is removed from queue. Change-Id: I7a33816a7ce4660513b047a7e54c3223a63c8cb3

Overview
OpenStack has the ability to publish notifications to a RabbitMQ exchange as they occur. So, rather than pouring through reams of logs across multiple servers, you can now watch requests travel through the system from a single location.
A detailed description of the notifications published by OpenStack is available here
