Move k8s to docker, optimize Dockerfile, add compose and monitoring setup

[CosminL-DEV]

This PR is the second part of the containerization process. Main changes include:

• Moved all files from the k8s folder to the docker folder, following best practices for structure and clarity.
• Kubernetes usage is now located in docker/kubernetes-example.
• Improved the Dockerfile to reduce the image size.
• Added a docker-compose file for easier local testing and deployment.
• Included necessary files for Grafana and Prometheus to start correctly within the dockerized environment.

These updates enhance the project’s organization, optimize Docker usage, and facilitate monitoring setup.
