Add a configurable `dimension_client::strip_k8s_label_prefix` option (default: true) that strips the `k8s.<resource>.label.` prefix from Kubernetes resource label keys before sending them as SignalFx dimension properties. This maintains backwards compatibility with existing SignalFx consumers while supporting the new OTel semconv label key format emitted by receiver/k8s_cluster. Assisted-by: Claude Opus 4.6

…efix from dimension property updates. (open-telemetry#47494) Add `dimension_client::strip_k8s_label_prefix` option to strip `k8s.<resource>.label.` prefix from dimension property updates. Once open-telemetry#47493 is merged, the k8s cluster receiver will emit Kubernetes resource labels in entity events with the `k8s.<resource>.label.` prefix per OTel semantic conventions (e.g. `k8s.pod.label.app`). When `strip_k8s_label_prefix: true` (the default), the SignalFx exporter strips this prefix when forwarding labels as dimension properties, preserving the existing SignalFx behavior (e.g. `app`).
