{{/*
Get Pod Env
- Merges default environment variables (if used) with component environment variables.
- If using defaults, will pull out OTEL_RESOURCE_ATTRIBUTES from the list to be reused later.
- An environment variable named OTEL_RESOURCE_ATTRIBUTES_EXTRA will have its value appended to the value of the
OTEL_RESOURCE_ATTRIBUTES environment variable if it exists.
- The OTEL_RESOURCES_ATTRIBUTES environment variable will typically use Kubernetes environment variable expansion and
should be last.
