test logs print:
[2023-08-22T10:18:14-04:00] 💿 Install image via installer(ISO) on VM
WARNING --os-type is deprecated and does nothing. Please stop using it.
We were using greenprint for failures, which makes it hard to quickly
find where the tests failed. This switches errors to use redprint, and
adds it to places that were simply using echo before doing an exit 1.
