Setting kubernetesResourcesLabelsAsTags brakes helm templating since 3.73.1

[alexstojda]

Since agent chart version 3.73.1 helm templating fails when setting datadog.kubernetesResourcesLabelsAsTags.

Pretty sure the issue stems from this commit 0802799 by @gabedos

How to reproduce

Run helm template datadog datadog/datadog with values:

datadog:
  kubernetesResourcesLabelsAsTags:
    '*': 'kube_%%label%%'
    'labels.mycompany.com/foo': 'bar'

You should get an error:

Error: YAML parse error on datadog/templates/cluster-agent-rbac.yaml: error converting YAML to JSON: yaml: line 19: did not find expected alphabetic or numeric character

Hello @alexstojda, you should be able to use datadog.kubernetesResourcesLabelsAsTags with the following configuration.

kubernetesResourcesLabelsAsTags:
    pods:
      "*": "kube_%%label%%"

This original PR should provide more context, particularly in the helm-charts/charts/datadog/values.yaml file providing examples to configure this value.

Hope this helps!

Ah, this is kind of a breaking change, would have been useful to mention that in the changelog too 😅

Thanks
