[REQ][Qt5] Optional TimeOut

[luStopai]

Is your feature request related to a problem?

Yes

Please describe.

I think Qt5 doesn't manage timeout problems by default. This means that if there is a timeout because of a firewall or an unresponsive server, the connection won't die since there is no mechanism to solve this situation.

Describe the solution you'd like

The usual solution is to set a Qtimer with setsingleshot=true and a timeout, then connect this qtimer timeout() signal to the QNetworkReply abort() slot. If the response happens before the timeout, then the timer has to be stopped. I think you can do this by connecting the finished signal of QNetworkReply to stop slot of the timer, or by calling stop manually when processing the response.

I thought of maybe making the constructor of the generated client depend on an optional timeout with a default value, for example MyConstructor(int timeout = 30). Another option is to set the optional timeout before making a request by using a simple setter.

I've also read about a complementary solution for a similar problem that consists in to combine the use of a qtimer with downloadProgress to check if a download has stopped or is slower than a threshold then abort the connection.

Describe alternatives you've considered

None comes to my mind
