Service Catalogue - Group sizes of a service in one service main page

[MiquelBonet]

As there exists one TOSCA file for each size of a service, at the moment, in the Service Catalogue, a service is shown as many times as sizes it has available.

They should be grouped in a way that first you enter to the main page of the service and then you choose the size of the service you want.

This way we avoid having the Service Catalogue full of copies of the same service.
