`--test-easyconfigs-pr` will pull in the PR (just like `--from-pr`), and submit a test report back in the PR (via a gist)

`--from-pr` can be used to test PRs, but also to simply pull in easyconfig files from a PR (merged or not merged yet) to actually build them in produciton; this could be useful in between EasyBuild releases, if someone can't wait for the next release and doesn't want to pull in the PR manually...
