Subject: [PATCH] Add configurable env vars to health-monitoring-agent
 DaemonSets

Introduce a .Values.env range block in both the nvidia and non-nvidia
HMA DaemonSets so custom environment variables can be injected via values,
rendered before the built-in NODE_NAME/NODE_IP fieldRef vars.
Add env: [] default in values.yaml.
