> OpenTelemetry Java agent instrumentation

This instrumentation enables consumer messaging spans for Spring Kafka listeners.

- **Name**: `spring-kafka-2.7`
- **Scope**: `io.opentelemetry.spring-kafka-2.7`
- **Target versions**: `org.springframework.kafka:spring-kafka:[2.7.0,)`
- **Library**: https://spring.io/projects/spring-kafka

## Telemetry

- **Span attributes**: `messaging.batch.message_count`, `messaging.client_id`, `messaging.destination.name`, `messaging.destination.partition.id`, `messaging.kafka.consumer.group`, `messaging.kafka.message.key`, `messaging.kafka.message.offset`, `messaging.message.body.size`, `messaging.operation`, `messaging.system`, `kafka.record.queue_time_ms`

## Configuration

| Option | Type | Default | Description |
| --- | --- | --- | --- |
| `otel.instrumentation.messaging.experimental.capture-headers` | list |  | A comma-separated list of header names to capture as span attributes. |
| `otel.instrumentation.kafka.experimental-span-attributes` | boolean | false | Enables the capture of the experimental consumer attribute `kafka.record.queue_time_ms` and `messaging.kafka.bootstrap.servers`. |
| `otel.instrumentation.messaging.experimental.receive-telemetry.enabled` | boolean | false | Enables experimental receive telemetry, which will cause consumers to start a new trace, with only a span link connecting it to the producer trace. |
