[Task] Manage cache in dependency loading

[taorepoara]

What should be done

In order to reduce the data load during updates, manage cache using the HTTP caching norms.

Technical recommandation

Save the Etag header when a resource is loaded and send it in the requests during update.
Save the cache values in the Dofigen lock file.

Ecological concerns

This cache would reduce the ecological footprint.
