Right now if you have a sidecar like istio's (istio/istio#19395) with an EmptyDir and the main service without it; the pod is excluded

A work around is to set the annotation

   cluster-autoscaler.kubernetes.io/safe-to-evict: "true"

but that applies at the whole pod level and one would need to duplicate the logic checking for volumes to decide true/false

Can we instead have an annotation like

cluster-autoscaler.kubernetes.io/ignore-container: istio-proxy

(or maybe a pattern, ignored-containers: pattern)

That would skip said container(s) [volumes] for the determination of whether a pod is evictable or not ?
