Update realtime containers

[christophfroehlich]

Apply changes from the guidelines added with ros-controls/realtime_tools#347

• I changed all Boxes to use the messages itself, instead of a smart pointer to it.
• Messages get pre-allocated and saved later for the case that any try_get fails in the RT thread
• I refactored the steering_controllers_lib a bit, to have the same timeout logic that the mecanum_controller has. This needed some updates of the tests, too.
• Apart from that, the behavior of all controllers should not change at all

LGTM

May be we should check here with std::all_of that all of the data elements are finite values

[christophfroehlich]

This would be a behavior change right? maybe we can do that in a follow-up PR?
