Logs edit events in openfoodfacts-query

[alexgarel]

Problem

We started https://github.com/openfoodfacts/openfoodfacts-events/ but discussing together we realize it would be better to store events in openfoodfacts-query as it would enable crossing events with facets.

Solution

Log events in openfoodfacts-query.

Add a table that correspond to the changes.sto with useful information: date, user, device, changed fields.

Add events from redis stream.

Add an API to query that with filtering options.

After that we might want to log more events:

• scans
• producers imports
