Description of problem:

In a couple of 4.9 bugs, we've seen instances where the kubelet is logging that a pod attempted an illegal phase transition, e.g.

https://bugzilla.redhat.com/show_bug.cgi?id=1998193#c16
https://bugzilla.redhat.com/show_bug.cgi?id=1997478#c25

I suspect this may be related to the 4.9 pod lifecycle refactor, as this doesn't appear to have been present in earlier versions.

This log message is invoked here: https://github.com/openshift/kubernetes/blob/f181eb2582e1649676395f25710c14b427b3369c/pkg/kubelet/kubelet_pods.go#L1480-L1484

It's only possible when a terminal pod (failed or succeeded) attempts a phase transition.
