Support Assigning Multiple Pod Labels via Helm Chart

[karthiktumu]

The current helm chart supports adding only one Pod label via the helm chart.

Below is our values file and error we're seeing when trying to assign multiple pod labels

Values.yaml

octopus:
   pods:
      labels:
         key1: value1
         key2: value2
         key3: value3

Error

Error: YAML parse error on octopusdeploy-helm/templates/statefulset.yaml: error converting YAML to JSON: yaml: line 26: mapping values are not allowed in this context

The helm chart statefulset template has to be changed as below

Current Pod Labels Block

      {{- if .Values.octopus.pods.labels }}
      {{ toYaml .Values.octopus.pods.labels | indent 2 }}
      {{- end }}

Proposed Pod Labels Block

      {{- with .Values.octopus.pods.labels }}
      {{ toYaml . | indent 2 }}
      {{- end }}
