Allow multiple mounts in StatefulSet volume zone placement
We have some heuristics that ensure that volumes (and hence stateful set
pods) are spread out across zones. Sadly they forgot to account for
multiple mounts. This PR updates the heuristic to ignore the mount name
when we see something that looks like a statefulset volume, thus
ensuring that multiple mounts end up in the same AZ.
Fix#35695
