Support for std::chrono as transferTimeout type

Provide users with means to use more modern time/duration type.

Please note that since QTimer does not currently support
timeouts larger than 'int' milliseconds, the limit on how long
durations can be expressed, remains. This should not
be an issue in practice with network requests, as a typical
int32 system can express timeouts of ~24 days.

[ChangeLog][QtNetwork][QNetworkAccessManager] Add std::chrono
support for transfer timeout.

[ChangeLog][QtNetwork][QNetworkRequest] Add std::chrono support
for transfer timeout.
