SetEnv and GetEnv

STATUS Sketchy: Author brainstormed ideas and recorded them - read with caution

Instead of using artifacts:reports:dotenv:, use the setenv/getenv pattern defined in the all-global element. It relies on job artifacts, which are more tightly constrained and can be saved.

The files we save with variable information receive a .html filename extension so they can be easily viewed in the artifact browser in GitLab (otherwise a .sh or .txt extension would make more sense).
