Code Issues Proposed changes
stacktach/tests/unit/test_worker.py
Manali Latkar 3f6542f049 - Added logic to populate generic rawdata and glance rawdata 
- Moved the responsibilty to save rawdata to the notification classes
- Notification are now created based on exchange instead of routing_key since routing_keys
  may not be unique across services
- Separate consumers are now created for every exchange specified in the config
- Each consumer is started in a separate process
- Introduced notification factory and the config module
