Enable marking judging machines to be allowed/disallowed to judge in CPU mode

        Details

          Description

          If you want to connect some instances of SIO2 to sioworkersd and one of these instances wants to judge tasks in CPU mode, then we can't use all judging machines that we have, because they have different CPUs. If we can mark each of judging machines that it is allowed (or disallowed) to judge in CPU mode, then we can use all judging machines and some of them would be used only in VCPU mode.

            Moreover, judging in CPU mode must be exclusive: only one task may run on a multicore machine, to prevent interferation. To achieve this, we need a proper read-write-style locking mechanism.

            Solved by introducing Prioritizing Scheduler (SIO-1930).
