Subject: [PATCH] test/e2e: Support logging an individual resources' state to
 stdout

Add initial support for debugging individual Kubernetes resources,
executing arbitrary shell commands, etc. This is mainly useful in the
context of debugging cluster-scoped resources (e.g. the Operator API)
that don't necessary fit into the test/e2e/collect-ci-artifacts.sh
gather script.
