Request FrameAligned view, as in ROS1

[jowaibel]

In ROS1's rviz, there used to be a FrameAligned view that allowed to align the view exactly with a target frame. This is crucial for, e.g., a flight simulator where the user wants to see the view of the aircraft moving in 6 degrees of freedom. (In this case, the target frame would be the body frame.)

ThirdPersonFollower would work for a robot that moves on the horizontal plane only but not for an aircraft moving and rotating in 3 dimensions.

I cannot understand why this feature has not been ported and nobody asked for it since rviz2 came out. It would highly appreciate if it could be added to rviz2. Thank you very much!
