A-la-carte: no code change

Macro: need to get the data from SDCCsarParser.                             

• With Dublin, a new mode is available in SO to instantiate a service : the "macro" mode.
• In SDC, a service can be declared with an instantiationType equal to "A-la-carte" or equal to "Macro". This information is then available in the Tosca service definition file.
• When "Macro" mode is choosen for a service, the SO will use different kind of BPMN workflow.
• This "macro" mode need to be managed by NBI.
• NBI needs to look at service definition in Tosca file, select the mode, build the "macro" request toward SO when service instantiationType is "Macro".
