Readiness probes should be ignored on initContainers

[irasnyd]

The Kubernetes documentation states that readiness probes are not supported on initContainers:

https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

Also, Init Containers do not support readiness probes because they must run to completion before the Pod can be ready.

Based on this, I think that lack of a readiness probe should be ignored for initContainers. This would bring my cluster's score up a bit. 😃

Great catch, thanks! We'll work on fixing that.
