This is a bit opinionated, but some comments in integration tests do not
really help to understand the nature of the tests being performed by
stating something very obvious, like
# run busybox detached
runc run -d busybox
To make things worse, these not-so-helpful messages are being
copy/pasted over and over, and that is the main reason to remove them.
