Provide RedirectingClient

A user has to do it by himself/herself to handle a redirect response:

WebClient client = ...
AggregatedHttpResponse res = client.get("/redirect").aggregate().join();
String location = res.headers().get(LOCATION);
if (location != null) {
    AggregatedHttpResponse redirected = client.get(location).aggregate().join();
} else {
    ....
}

It’s a little verbose so it will be nice if we provide RedirectingClient.

Oops didn’t realize they treat child logs differently 😅

If the call is client -> RedirectingClient -> LoggingClient or (MetricCollectingClient) then, the redirecting is logged as well.

If the order is different which is: client -> LoggingClient or (MetricCollectingClient) -> RedirectingClient the redirecting is not logged.

It’s described here. http://line.github.io/armeria/client-retry.html#retryingclient-with-logging 🤔
