We have started seeing VM boot and test run steps failing
without reporting which scenario failed or why. For example,
https://prow.ci.openshift.org/view/gs/origin-ci-test/pr-logs/pull/openshift_microshift/2660/pull-ci-openshift-microshift-main-microshift-metal-tests/1729555422999744512

We need to improve the output of those parts of the framework to give
us more hints about what is going wrong.
