Evaluation and restructuring of tools

[dkroenke]

Brief feature description

For making iceoryx more stable, we need to look for better tooling to do code analysis and support the developer. We should also take a deeper look into the ROS side what there is used, e.g. ament_lint. Proposals are welcome!

List of common tools from ROS2:

• ament_cmake_copyright <https://github.com/ament/ament_lint/blob/master/ament_cmake_copyright/doc/index.rst>_ : a copyright linter which checks that copyright statements and license headers are present and correct (already integrated)

• ament_cmake_cppcheck <https://github.com/ament/ament_lint/blob/master/ament_cmake_cppcheck/doc/index.rst>_ : a C++ checker which can also find some logic tests (Not to be used because there is already clang-tidy)

• ament_cmake_cpplint <https://github.com/ament/ament_lint/blob/master/ament_cmake_cpplint/doc/index.rst>_ : a C++ style checker (e.g. comment style)

• ament_cmake_lint_cmake <https://github.com/ament/ament_lint/blob/master/ament_cmake_lint_cmake/doc/index.rst>_ : a cmake linter (Not to be used with ament to avoid hard ROS dependency)

• ament_cmake_uncrustify <https://github.com/ament/ament_lint/blob/master/ament_cmake_uncrustify/doc/index.rst>_ : a C++ style checker (Not to be used because there is already clang-format)

Additional ToDos for tooling:

• [x] restructure scripts in tools folder
• [x] lint shell scripts
• [x] tidy-up CI jobs
• [x] update dockerfile to Ubuntu Focal LTS

I think we already have ament_cmake_copyright since #346.

Since we already use clang-format I'm not sure if we need uncrustify. A pre-commit hook for clang-format would be nice, though

We currently have Address, Leak & Undefined Behaviour Sanitizers. Clang has some more tools in their basket.

• https://clang.llvm.org/docs/ThreadSanitizer.html (clang site states that they are in beta)
• https://clang.llvm.org/docs/MemorySanitizer.html (all dependent libs including libc++ should be recompiled with special flags)
