/kind bug

cinder-csi-plugin node plugin DaemonSet definition (the manifests and the chart) deploys with hostNetwork: true, but it is missing dnsPolicy: ClusterFirstWithHostNet, so node's DNS config is always used, bypassing cluster's DNS cache. This can negatively impact performance of the external DNS.

I'll attach a PR with optional dnsPolicy parameter for the Helm chart, allowing users to set the policy they prefer.
