feature: Go net/http -> wasi:http Proxy

[lxfontes]

Helpers to proxy HTTP Requests from Go's standard library over to WRPC wasi:http.

Proxying uses a custom http.RoundTripper implementation that forwards requests to the component. In this example we forward to a single target ( http-http_component ).

transport := wrpchttp.NewIncomingRoundTripper(wasmcloudprovider, wrpchttp.WithSingleTarget("http-http_component"))

wasiIncomingClient := &http.Client{
  Transport: transport,
}

wasiIncomingClient.Get("http://localhost:8080/proxy")

The provided example is a HTTP <> WASI Proxy analogous to https://github.com/wasmCloud/wasmCloud/tree/main/crates/provider-http-server
