feat(main): --packages-select and --packages-skip

[Guillaumebeuzeboc]

Hello,
With this feature, I added options to only process or skip packages like colcon can do.
Rosdep already support COLCON_IGNORE and CATKIN_IGNORE, but with these flags no need to manually place those files.

This way, we can run rosdep over ros2 demos and ignore only a few examples.
Example:

git clone https://github.com/ros2/demos.git
cd demos
rosdep install --default-yes --ignore-packages-from-source -s --from-paths . --packages-skip "lifecycle lifecycle_py"

Hi @cottsay, could we get an approval for the ci workflow to run please?
