feat(backend): spawn the notifications service + basic test (#9464)

We want to send emails on a schedule, in response to events, and be
expandable without being overbearing on the amount of effort to
implement. We also want this to use rabbitmq and be easy for other
services to send messages into.

This PR adds the first use of the service to simply show a log message


### Changes 🏗️

<!-- Concisely describe all of the changes made in this pull request:
-->
- Adds a new backend service for notifications
- Adds first notification into the service -> Agent Execution
- Adds spawning the notification service

Also 
- Adds RabbitMQ to CI so we can test stuff
- Adds a minor fix for one of the migrations that I thought was causing
failures, but isn't but the change is still useful
