forceInternetOnOffSimulation property
If you have a configuration object that specifies if the internet connection should be
simulated as on or off, you can replace this method to return that configuration value.
For example: CheckInternet.forceInternetOnOffSimulation = () => Config.isInternetOn;
Return true if there is internet, and false if there is no internet.
Return null to use the real internet connection status.
