`PlacementPolicy` type now provides methods to work with QL-encoded policies. System network parameters can be read using dedicated method without iterating. Applications can work with `PlacementPolicy` variables directly so there is no need to use pointers. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
