ci(functional-tests): add functional tests scripts

- Add scripts/functional-tests.sh script
- Add `download_artifacts` functions, allowing to retrieve artifacts of a gerrit patch
- Robot: redirect output of topology build to files, thus preventing robot from hanging
- Share folders between host and containers with the :z flag
- Use sudo to install executable in docker-compose scripts, as the user of the docker is not root anymore
- Makefile: decouple installation and build
