Is this a BUG REPORT or FEATURE REQUEST? (choose one): Feature Request

Version of Helm and Kubernetes: Helm v2.16.1 Kubernetes v1.17.0

Which chart in which version: fluentd-elasticsearch-6.1.0

What you expected to happen: Instead of creating a service, i'd like to be able to have the fluentd pods in the DaemonSet listening on the same port on every node, using hostPort in the pod template spec.

I've implemented it like this for myself, by adding service.ports[].hostPort:
