This commit enables WebSocket message spans to be linked back to their
originating HTTP upgrade request spans using OpenTelemetry span links.
Key changes:
1. VertxWebsocketHost: Capture HTTP upgrade span context using reflection
- Avoids compile-time dependency on OpenTelemetry
- Stores span context in RoutingContext during WebSocket upgrade
2. VertxWebsocketPeer: Store handshake span context
- New field to hold the HTTP upgrade span context
- Persists for the lifetime of the WebSocket connection
3. VertxWebsocketSpanDecorator: Custom span decorator for vertx-websocket
- Collects span contexts from target WebSocket peers (Producer)
- Supports multiple span links (sendToAll scenarios)
- Uses reflection to avoid component dependencies
4. OpenTelemetryTracer: Create span links from collected contexts
- Extract span contexts from exchange headers
- Support both direct SpanContext objects and serialized format
- Add links to spans during creation
5. VertxWebsocketConstants: Add HANDSHAKE_SPAN_CONTEXT_KEY constant
Benefits:
- Complete distributed tracing across HTTP and WebSocket boundaries
- Zero compile-time dependencies between components
- Supports both single and multiple span links
