Right now Jenkins forces us to use container images with a shell in order to run the "steps" block.  But some images I want to run, such as container-structure-test, don't have a shell (yeah, there's a debug version with a shell but there's another problem in there), and I'd like to have my stage "steps" be the "command" specified in my pod yaml.

Maybe this is a more fundamental Jenkins improvement rather than just the Kubernetes plugin...
