How can add APM tracing in below very simple go code, which use `net/http`.

```auto

package main
import (
    "fmt"
    "net/http"
)
func helloHandler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintln(w, "Hello, World!")
}
func main() {
    http.HandleFunc("/hello", helloHandler)
    http.ListenAndServe(":8080", nil)
}

```

Do we use [Built-in instrumentation modules | APM Go Agent Reference [2.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/go/current/builtin-modules.html#builtin-modules-apmhttp) module for that how?

New to golang and Apm. I see most of example either with mux or gin.
