added additional metricsets for the configmap

[gregbird101]

I wanted to add more metric sets to the configmap. I have added in a variable here and therefore you can add additional sets in the values.yaml when deploying.

humio-metrics:
  humioHostname: cloud.humio.com
  token: REDACTED
  additionMetricbeatMetricsets:
  - name: state_daemonset
  - name: state_resourcequota
  enabled: true
  es:
    autodiscovery: false
    tls: true
