Draft: chg: test: Refactor system tests to use jinja2 templates for setup
requested to merge nicki/replace-setup-sh-files-with-jinja2-templates into 4261-add-pytest-fixture-checking-test-artifacts
Some setup.sh scripts are used just to template the *.in config files with copy_setports. Create jinja2 templates from these *.in files and drop the no longer used setup.sh script.
