Event sourcing

[pedro-gutierrez]

Is your feature request related to a problem? Please describe.

This was identified by @coderbyheart while discussing how we could implement a shipments api in the toolbox. At the moment, our database model follows a classic design where:

• modifications are destructive
• there is no versioning
• there is little traceability

Describe the solution you'd like

Study and document the viability of turning the toolbox into an event sourced implementation. Where we natively store immutable events as our source of truth. Then we build projections where the outcome would be similar to what we currently have at the moment.

In Elixir, the best library for this purpose is https://github.com/commanded/commanded
