[EPIC] Project structure design

[eborghi10]

Is your feature request related to a problem? Please describe.

The repository is getting bigger and it should be separated in small repos to isolate functionalities.

Describe the solution you'd like

Functionalities like simulation/Gazebo models/navigation/mapping, etc, should be
migrated into different packages or repositories that group similar areas.

Important: a detailed concept must be defined before doing the migration

Describe alternatives you've considered

• The simulation and the real robot must be executed using the same launch file to avoid having duplicated code. See this as an example.
