Allow the watchdog to detect when the sandbox is stuck during setup.
The watchdog currently can find stuck tasks, but has no way to tell if the
sandbox is stuck before the application starts executing.
This CL adds a startup timeout and action to the watchdog. If Start() is not
called before the given timeout (if non-zero), then the watchdog will take the
action.
