EarlyHintsListener

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface EarlyHintsListener
```
Callback interface for receiving 103 Early Hints informational responses emitted by the server before the final response.
The listener may be invoked multiple times per request, once for each 103 received. It is never invoked for the final (non-1xx) response.

Implementations should be fast and non-blocking. If heavy work is needed, offload it to an application executor.
