Const ExperimentalSpecifies how traffic is distributed to endpoints for this Service.
This attribute aligns with the trafficDistribution field of the
K8s ServiceSpec.
Known values include PreferSameZone (prefer endpoints in the same zone as the client) and
PreferSameNode (prefer endpoints on the same node, fallback to same zone, then cluster-wide).
If this field is not set on the Service, the attribute SHOULD NOT be emitted.
When not set, Kubernetes distributes traffic evenly across all endpoints cluster-wide.
This attribute is experimental and is subject to breaking changes in minor releases of @opentelemetry/semantic-conventions.
The traffic distribution policy for the Service.
