Bigger refactoring:
* always use a bound service connection to start a vpn service as foreground service to fix remote excptions. These appeared if the system wasn't able to set the service as forground shortly after it was started * move vpn start logic from LaunchVPN activity to EIP service. LaunchVPN/VoidVPNLauncher is only used in case we need to ask the user for a permission. It reduces visual glitches when the transparent LaunchVPN activity appears and disappears
