RFC: Rename to Request-Id

[marijn]

Thanks for making an effort in building up the PSR middleware ecosystem.

I was wondering why you choose to name this package UUID. It seems its more about assigning identity to individual requests than about the particular ID used.

[oscarotero]

This middleware not only identify the request but also the response returned, so it's usefult for debug purposes. The UUID specification guarantee uniqueness across space and time, so I think it's a good name to identify a request->response cycle.

Thoughts @middlewares/contributors ?

I think it would be good to rename this package, or have a separate middlewares/request-identity package that would allow for both UUID and custom identifiers via interface:

interface RequestIdentityInterface
{
    public function getRequestIdentity(Request $request): string;
}

This interface would be useful in situations where the request identity could be provided via a header or other other means.

I don't know if it's possible to rename this package without break other things (like dependents). If it's problematic, a new package that deprecates this could be ok.
