Duplicated HostIP in telegraf-ds

[caiocfer]

When deploying telegraf-ds, in the daemonset the HostIP is duplicated, they are both written in the values.yaml and daemonset.yaml

  - name: HOSTIP
    valueFrom:
      fieldRef:
        fieldPath: status.hostIP

from: https://github.com/influxdata/helm-charts/blob/master/charts/telegraf-ds/values.yaml#L39

        env:
        - name: HOSTIP
          valueFrom:
            fieldRef:
              fieldPath: status.hostIP
{{ toYaml .Values.env | indent 8 }}

from: https://github.com/influxdata/helm-charts/blob/master/charts/telegraf-ds/templates/daemonset.yaml#L43

When deployed the telegraf-ds' daemonset it's found:

        env:
        - name: HOSTIP
          valueFrom:
            fieldRef:
              fieldPath: status.hostIP
        - name: HOSTNAME
          valueFrom:
            fieldRef:
              fieldPath: spec.nodeName
        - name: HOSTIP
          valueFrom:
            fieldRef:
              fieldPath: status.hostIP
