When printing services' tasks with `docker service ps` command, tasks are grouped only by task slot. This leads to interleaving tasks from different services when `docker service ps` is called with multiple services. Besides this, global services do not have slots at all and printing tasks for them doesn't group and doesn't properly indent tasks with \_. With this patch all tasks are grouped by service ID, slot and node ID (relevant only for global services) and it fixes issue 533.
