vty: Introduce support to set cpu-affinity and scheduler policy
Process willing to support this kind of configuration through VTY simply
need to call "osmo_sched_vty_init(tall_ctx);" during startup to register
the commands.
For multithreaded processes, new threads willing to get their
cpu-affinity mask according to VTY config should call
osmo_sched_vty_apply_localthread() (potentially after
setting the thread name through pthread_setname_np()).
