The global properties Json field of the Loop object must now contain a list of dcaeDeployParameters because we can now have multiple blueprints to deploy on DCAE.

They must be a map indexed by microservice name.

So we must change the LoopCsarInstaller.createGlobalPropertiesJson method so that it can add a unique element to that list (for backward compatibility with one unique blueprint)

The new code that will handle the creation of a loop based on a loop template will have to write the global prop json accordingly (but that's not part of this task)

Json should now be something like that:

"dcaeDeployParameters": {     

     "microservicename1":

           {          

            "param1": "value1", 

            "param2": "value2"

     },

     "microservicename2":

          {                           "param1": "value1",                        "param2": "value2"                  }

}
