Cluster metadata provider

To enable the cluster metadata provider feature:

  1. Ensure the Node Agents and the Datadog Cluster Agent can properly communicate.
  2. Create a Cluster Agent service in front of the Datadog Cluster Agent.
  3. Ensure an auth_token is properly shared between the Agents.
  4. Confirm the RBAC rules are properly set.
  5. In the Node Agent, set the environment variable DD_CLUSTER_AGENT_ENABLED to true.
  6. Optional - The environment variable DD_KUBERNETES_METADATA_TAG_UPDATE_FREQ can be set to specify how often the Node Agents ping the Datadog Cluster Agent.
  7. Optional - Disable the Kubernetes metadata tag collection with DD_KUBERNETES_COLLECT_METADATA_TAGS=false.
