Merge branch 'skia/deploy_in_ci' into 'master'
gitlab-ci: deploy with Gitlab CI/CD This MR is a proof-of-concept for deploying the Sith using Gitlab CI/CD. It leverage the CI variable to use a private key that is deployed for the `sith` user of `ae-web`. The `prod.sh` script shall do the rest. TODO before merge: * [x] Ensure the private key variable is protected (currently done, but may change during development to be used on this branch) * [x] Remove this branch from the `only:refs` list * [x] Change `test_prod.sh` for the real script See merge request ae/Sith!293
