Request some ephemeral-storage to avoid evictions

When a node is under disk pressure and wants to evict some pods, the
first rule is for pods that use more resources than requested
(https://kubernetes.io/docs/concepts/scheduling-eviction/node-pressure-eviction/#pod-selection-for-kubelet-eviction)

Requesting a bit here will prevent eviction of this pod, which is very
unlikely to use much anyway.
