Starts the streaming service if it's not up and running. This required adding the ability to run a detached process. By default, all child processes are killed when the parent process exits. Since detached child processes don't run with a console, they need to create sub- processes with CREATE_NO_WINDOW since otherwise a new console pops up, e.g. for every ssh command. Polls for 20 seconds while the service starts up. For this purpose, a BackgroundServiceClient is added. This will be reused in a future CL by a new stop-service command to exit the service. Also adds --service-port as additional argument to start-service.
