frontier squid pods may not get scheduled due to nodeselector if PVC is used

[rptaylor]

It looks like .Values.SLATE.LocalStorage has multiple functions; it enables use of a PVC but also applies a nodeselector:

On a standard cluster (at least on v1.21) it seems nodes do not have a storage: "local" label so by default the pod would not be able to run on any node out of the box. PVCs often use network storage anyway.
