ShouldSkipNodeFailureInjection returns true if we are attempting to inject a node failure that has already been injected for this given target If we're using staticTargeting, we should never re-select a target whose InjectionStatus is anything other than NotInjected, as we may be injecting into a pod that has been rescheduled onto a new node.
