docs: add redirect from /red_circle to camera article

* Allow using nans for most of services parameters
* Add terrain frame
* Remove yaw_rate parameter from most services
* Add set_yaw and set_yaw_rate services
* Correct order for pitch and roll everywhere to match XYZ convention
* Add simple_offboard/state topic
* Add essential tests
* Stop publishing setpoints when land called

 Выделение нескольких процессорных ядер для виртуальной машины может значительно повысить производительность симуляции. В наших испытаниях виртуальная машина, для которой было выделено одно ядро, не позволяла работать в симуляторе: окно Gazebo не реагировало на пользовательский ввод, сообщения ROS терялись. После выделения четырёх ядер для этой же виртуальной машины симуляция стала работать со скоростью 0.25 от реального времени.
 
 При этом не следует пытаться выделить для виртуальной машины больше ресурсов, чем доступно на основной системе.
