Adapt the code for ROS2 Jazzy

[RaduLucianR]

Re-think this package for ROS2 Jazzy.

• The C++ code that generates executors based on a YAML needs to be re-written to use processes and NOT threads, as it uses now.
• The analysis part doesn't work anymore because CARET is not ported to ROS2 Humble yet. So the latency analysis needs to be done by the new code.
• Perhaps the best is to archive this repository and split into 2 repositories:
  • one just contains the executor architecture generator in C++. This can be pre-compiled and run with a ros2 command and/or launch file. (the launch file could be useful so it can be passed to the latency code like the WCET estimation tool)
  • the other contains the latency analysis code based on ros2 trace
