omit URL's password when stringifying URL for segment name

[aloababa]

When instumenting an http.Client with an xray.Client, the segment name is based on url.URL.String which can lead to leak basic auth credentials in the segment name.

Is it possible to strip those credentials ? Or at least do the same that the stdlib does, they replace the password by a *** placeholder (like here: https://github.com/golang/go/blob/master/src/net/http/client.go#L1026)

I can see that you already strip the url query.

I can make a PR for it.

Thanks,

If you make a PR for it, then we can review it.
