v-m: vmstorage: Remove startup/ready probes

Kubernetes will not start additional Pods in a StatefulSet until the
existing ones are Ready.  This means that if there is a problem bringing
up, e.g. `vmstorage-0`, it will never start `vmstorage-1` or
`vmstorage-2`.  Since this pretty much defeats the purpose of having a
multi-node `vmstorage` cluster, we have to remove the readiness probe,
so the Pods will be Ready as soon as they start.  If there is a problem
with one of them, it will matter less, as the others can still run.
