Implement automatic redirects for requests regardless of the `HttpClient`

Request Statement

As Dart doc stated:

  /// Automatic redirect will only happen for "GET" and "HEAD" requests
  /// and only for the status codes [HttpStatus.movedPermanently]
  /// (301), [HttpStatus.found] (302),
  /// [HttpStatus.movedTemporarily] (302, alias for
  /// [HttpStatus.found]), [HttpStatus.seeOther] (303),
  /// [HttpStatus.temporaryRedirect] (307) and
  /// [HttpStatus.permanentRedirect] (308). For
  /// [HttpStatus.seeOther] (303) automatic redirect will also happen
  /// for "POST" requests with the method changed to "GET" when
  /// following the redirect.

The redirections will only happen in these circumstances.

But it might be great if other requests could follow redirections too.

Solution Brainstorm

Pseudo implementation:

int redirectTimes = 0;
Response response = await request(redirectTimes);
while (reseponse.isRedirect && redirectTimes < options.maxRedirects) {
  redirectTimes++;
  response = await request(redirectTimes);
}
if (response.isRedirect) {
  throw StateError('Maximum redirects limit reached.');
}
return response;

Start by locating Dio's current Dart HTTP client redirect handling and the existing redirect options. Review how redirects are handled for request methods and define tests covering additional methods and the maximum redirect limit. Done means supported requests follow redirects consistently and exceeding the limit is reported.
