Generate reports using Fission functions

[luksamuk]

Generate reports for existing entities (user, products) on PDF format. To do that, use Fission functions that should be deployed on Kubernetes. Notice that testing this feature will demand a Kubernetes cluster with Fission, Keda and RabbitMQ for testing.

• PDF generation on Golang: https://github.com/unidoc/unipdf
• Kubernetes-native object storage with MinIO: https://min.io/download?license=agpl&platform=kubernetes
• MinIO Golang SDK: https://github.com/minio/minio-go

It is possible that we would still need a REPORTS microservice for dispatching and providing information about report generation. Functions will generate the report as a way to make them asynchronous and to try and break blocks in many pieces that will then be aggregated.

Needless to say, this requires architecture analysis before actual development:

• [x] Deployment documentation
• [ ] Go Version Manager usage documentation
• [ ] Proof-of-concept
• [ ] Architectural analysis and graphs (ad-hoc only)
• [ ] Tool automation for generating functions

This will demand proper architectural analysis as discussed before, so it should be on hold until the architectural bits are done.
