Enable CloudSim Plus Automation to work in the reverse way

[manoelcampos]

CloudSim Plus Automation reads a simulation scenario from a YAML file and instantiates the Java objects to build and run the simulation. It would also make the other way around: from a scenario built using Java, provide methods to generate the respective YAML file.

The developer would rely on a new CloudSim Plus Automation class to be used inside his/her Java simulation code to export the simulation scenario. This feature would be useful to enable creating YAML files from already existing simulations written in Java. It will allow such a scenario to be shared and easily changed.
