Describe what you'd like to see

Create a plugin to read events coming from the core api, and alert users based on those events.

TODO's:

• Create a database driven settings system to keep track of per-user notification settings (recommend postgresql as a backend)
• Read from the OQM events queue, send alerts as necessary along configured channels
• Support different channels for sending alerts (at least 2):
  • Email
  • Slack
  • Zulip
  • (add others if applicable)
• Documentation on how the plugin works; any additional configuration?
• Automated test to prove functionality (stretch goal)
