fix(go/sdk): Populate full url in request object

[adamreese]

This changes the request object to parse the full url rather than the uri. This correctly populates the Scheme, Host, and Query fields.

url.URL{
        Scheme:      "http",
        Opaque:      "",
        User:        (*url.Userinfo)(nil),
        Host:        "localhost:3000",
        Path:        "/hello/world",
        RawPath:     "",
        OmitHost:    false,
        ForceQuery:  false,
        RawQuery:    "foo=bar",
        Fragment:    "",
        RawFragment: "",
    },
