Support for fasthttp.Client

[joanlopez]

Background

fasthttp is an alternative to Go's native net/http network library. It is written to be significantly more performant at scale; in some cases, it is ~10x faster than the standard library. It is used widely and is well-maintained.

Moreover, this project already have support for fasthttp handlers: issue & merged pull request.

The Ask

Therefore, it'd be helpful if aws-xray-sdk-go could work out-of-the-box with fasthttp client as well.
The client implementation is different enough to make it not trivial to use as-is.

Hi @joanlopez - thanks for the feedback! We'd be happy to take a look at a PR for a new client instrumentation, however at this time we will not be able to add new instrumentations on our roadmap.

Alternatively, we would recommend you check out the AWS Distro for OpenTelemetry Go, which provides first-class fasthttp support and support for the X-Ray backend! https://aws-otel.github.io/docs/getting-started/go-sdk

We are always open to feedback that you can open here: https://github.com/aws-observability/aws-otel-go

Sure, sounds like a great alternative! :) Could you please point out to any code example / documentation page with examples or information about how to instrumentate the SDK with the fasthtt, please? Thanks!
