CICD / Docker image

[sylvain-morin]

Create a new config file (config.docker.js) using ENV variables (injected by docker compose or kubernetes manifest)

Rework the gitlab CI files to have 3 workflows:

• main: build the main branch and push 2 docker images, tagged "latest" and using the git commit ID
• dev: build any dev branch and push a docker image, tagged using the (sanitized) branch name
• pr: build any PR, running only the test (no docker image creation/push)

I don't understand enough about Docker to provide constructive criticism here, but just so I understand what's happening, the Github workflows just push new images to Docker Hub? They don't actually deploy those images onto any of our machines?

[sylvain-morin]

Indeed @kueda, the last step of the workflow is pushing docker images to the docker registry.

The deployment of these images on the kubernetes cluster will be handled in a separated workflow, for security reasons. The fact that our github is public requires to be really cautious.

I requested a couple changes in config.docker.js but otherwise this looks good to me
