### Expected behavior

It should be possible, when using net.request, to set redirection options. The `ClientRequest` constructor options should contain a "redirect" attribute, with possible values "follow", "error" or "manual" (like window.fetch), and defaulting to "follow".

Also, when a redirection did happen, it should be possible to know it did, and at least get the URL to which we were redirect (for example as an attribute of IncomingMessage).

### Actual behavior

It is not possible to stop redirections from happening, or even to know that it happened and get the new URL.

### How to reproduce

Use net.request on any URL that does a redirect.
