Description

net/http expose RoundTrip so it can integrate with opentracing by overwrite the RoundTrip function. while fasthttp client don't implement such interface and do not provide middleware. The only way to integrate with opentracing is overwrite all method of fasthttp client, but it is not graceful.

Contributor guide

Research direction
The issue requests a graceful way to integrate OpenTracing with the fasthttp client, similar to net/http's RoundTrip mechanism. Research the net/http opentracing integration in opentracing contrib/go stdlib (nethttp/client.go) to understand the approach. Examine fasthttp's client source code (client.go) to identify where a middleware or interceptor could be added without compromising performance. Consider designing a client wrapper or method level hooks. Discuss the proposed design with maintainers in the issue comments.
