Jordan Petridis a99cdc8909 docker: allow to specify the branch to pull for various repos ... Declare an docker build-arg [1] and use it whenever cloning one of our repositories. If the buildarg is not specified, the variable defaults back to 'master' and thus the current behavior doesn't change. From the .gitlab-ci.yml file, when building pass the GST_UPSTREAM_BRANCH that's defined from the ci_template as the buildarg so we will be building the corresponding branches for the docker images.
