Beep VPS

Description

For the Beep project, we need a VPS to host some services and the different environments of beep (staging, prod). The infrastructure would like to be as automated as possible. For start we will need to install a k3s cluster on a VPS after this the different services will be deployed on the cluster by CI/CD with terraform.
