Issue:

Dear developers,

I would love to have access to the _ament_cmake_python_get_python_install_dir() CMake macros officially publically.

The reason for this is that when ones uses python bindings we need to be able to get the PYTHON_INSTALL_PATH in order to have a consistent installation of the package.

So far I have been calling directly the macros (_ament_cmake_python_get_python_install_dir) in my CMakLists.txt which is never officially recommended as the macros start with and underscore.

Solution:

We could simply remove the underscore before the macros name and therefore allow users to know where ament is going to install the python module.

WDYT?
