Improve setup.py script

[tarelli]

Add a command line interface to the script to guide the user to specify which bundles they want to install which will also update config.json and geppetto.plan.

• [x] Core bundles (always installed) "org.geppetto.model" "org.geppetto.core" "org.geppetto.simulation", "org.geppetto.frontend"
• [x] Optional bundles, all the other ones, we ask a question for each one of them.
• [x] We update config.json
• [x] We update pom.xml
• [x] We update geppetto.plan
• [x] If the selected bundles do not exist (at the same level of org.geppetto) we also clone them at the end (the url comes from the config.json) otherwise we just update the various files
• [x] Create a PR

Additional modification - have an "interactive" and a "non-interactive" mode. The non-interactive mode will just include the default scripts.

Haven't done anything on this yet, will work on this for sprint 75.

I have a setup_optional script - this allows the user to select the repos I need. Having said that, I am not sure whether I should merge this with @slarson 's setup script or whether the two should be kept separate.
