Fix symlink-install compilation

[youliangtan]

Issue

This fix is partly to address the potential issue when build with --symlink-install. open-rmf/rmf#24.

Fix

Previously the rmf_fleet_adapter_python will invoke a cmake build from setup.py. This PR will remove the need of setup.py, and install the pkg via ament_python_install_package() in the CMakeList.

Also, the package ament_python is removed, and replaced with pybind11_vendor. This will be installed during rosdep.

Test

# Compile, with and without `--symlink-install`
ros2 run rmf_fleet_adapter_python test_adapter.py

-- in-progress --

• Pending colcon test

This fixes the symlink issue for me as well, I guess we should get colcon test to work first? Does the rclpy matching code help?

Added the test 86b4a7f

colcon test --packages-select rmf_fleet_adapter_python --event-handlers console_direct+

Last but not least, once this is merged, users will need to re-run rosdep update & install sequence to ensure pybind11-vendor is locally installed.

Awesome! I tried building / testing / sourcing and importing the python bindings and it's working.
I agree that needing rosdep update / install is not ideal but that shouldn't be an issue for binary builds, while for source builds we can point it out to users.
