Create a setter method to sets Connection read timeout

[kobikis]

In the following example the Connection timeout is 7sec and the url latency is 5sec but i'm getting java.net.SocketTimeoutException: Read timed out

`
@RunWith(SpringRunner.class)
public class FetcherConcurrentClientApplicationTests {

@test
public void simpleTest() {
Document doc = null;
long startTime = System.nanoTime();
try {
doc = Jsoup.connect("http://httpstat.us/200?sleep=5000").timeout(7000).get();
} catch (IOException e) {
e.printStackTrace();
}
long processingTime = System.nanoTime() - startTime;
System.out.println("Processing time: " + TimeUnit.NANOSECONDS.toMillis(processingTime));
assertNotNull(doc);
}
}
`

It's because that when JSoup create a connection it configure the Connection readTimeout to half of the request timeout.

`
private static HttpURLConnection createConnection(Connection.Request req) throws IOException {
final HttpURLConnection conn = (HttpURLConnection) (
req.proxy() == null ?
req.url().openConnection() :
req.url().openConnection(req.proxy())
);

        conn.setRequestMethod(req.method().name());
        conn.setInstanceFollowRedirects(false); // don't rely on native redirection support
        conn.setConnectTimeout(req.timeout());
        conn.setReadTimeout(req.timeout() / 2);
