Major reordering

[MFernandezCarmona]

Changelog:

• Removed several packages that made no sense here. hri_simulation nav_simulation iliad_human_local_navigation taros19_experiments constrain_maps

• Renamed remaining accordingly. base_simulation -> iliad_base_simulation dynamic_constraints -> iliad_qtc_constraints twist_controller -> iliad_citi_controller

• Still to do before considering the PR:

• [x] Citi xacro file in iliad_base_simulation should go to oru nav. A PR has been created

• [x] Changes here will affect to iliad_launch_system. Create PR accordingly.

• [x] Check maintainer mails.

Sweet. You already open a WIP pr as then we'll see where it breaks. But, yes, maintainer emails should be setup for that first. But after that, open PR and keep pushing.

@marc-hanheide I think we are ready to merge branch tidy into master. I already created the pr to sync package name changes here.

Tested in simulation. Works fine. Will test on robots now.
