Add a script for downloading artifacts from the build job in a gerrit pipeline, so it can be used in the hwtest job job.
pipeline: <--- URL to the pipeline is passed to all jobs parallel: sequential: build <--- artifacts are here hwtest <--- will call the new script with the pipeline URL lint binpkgs ...
Add a new test that flashes the firmware from the previous build job and runs tests against it. Tests are intentionally from the master branch for security reasons.
