DbSpanNameExtractor

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 SpanNameExtractor<REQUEST>
```
Extractor of the span name for a request. Where possible, an extractor based on semantic conventions returned from the factories in this class should be used. The most common reason to provide a custom implementation would be to apply the extractor for a particular semantic convention by first determining which convention applies to the request.
