[♻️ refactor] Use docker+swarm for deployments

[Fredkiss3]

What is the reason to do this refactor ?.

Using pm2 is not enough and can instead cause moments where the app is down because it reuses the same codebase.

Describe the work that needs to be done

Move our deployment pipeline to docker and docker swarm and see between nginx & docker swarn which should be our load balancer.
