This piece will query both Issues and Preferences and create Notifications based on them. It will then write the new Notifications to a message queue.

Notes:

• Be aware that some issues might be flagged by multiple "alerts", therefore we have to keep track of all alert-sources for each notification.
• If I add new alert, I should have the option to populate it for certain time period retroactively
• Incorporate scenario: I remove one of my alerts and I (may) choose in UI to remove all its notifications right now (e.g. I added it yesterday and I didn't realize it is high-volume alert)

Please refer to the Architecture documentation for more information.
