[newrelic-logging] Helm Chart has Incomplete Env Variables

Bug description

[Originally posted by @druidsbane in the newrelic-fluent-bit-output repository]

Version of Helm and Kubernetes

<Please provide this information, @druidsbane, @jasonchester>

Which chart?

newrelic-logging (current version)

What happened?

The pods were unable to get host status until I added:

- name: HOSTNAME
  valueFrom:
    fieldRef:
        apiVersion: v1
        fieldPath: metadata.name

This also happened on Azure Kubernetes Service (AKS) and was fixed by the above addition.

Can we get this added to the Helm chart and the regular deployment file?

We have same issue. We've added HOSTNAME env but issue still goes on. We use aks 1.17.13. Any ideas ?
