    Doc: pacemaker.service: Recommend not to limit tasks
    
    Systemd v227 introduced the "pids" cgroup controller:
    https://github.com/systemd/systemd/commit/03a7b521e
    
    From systemd v228, it's enabled for all services by default, and the
    global default of TasksMax was 512:
    https://github.com/systemd/systemd/commit/9ded9cd14
    
    The limit could be be easily hit since any processes/threads spawned
    from the unit count, such as the "ocf" type of resources.
    
    In systemd v235, the default TasksMax= has been effectively changed to
    4915:
    https://github.com/systemd/systemd/commit/79baeeb96
    
    But it still could be a potential issue for cluster with heavy workload.
    
    Generally it probably doesn't make much sense to set such a limit for a
    resource manager like pacemaker.
    
    This commit recommends the same as the docker project does:
    https://github.com/moby/moby/commit/33a8ab29ed
