Adapt renderer to manage 100GE service on Switch

Adapt renderer to manage 100GE service on Switch

- Add new method in OpenRoadmInterface221 to create ODU4 interface as
an HighOrder interface (to support 100GE flow)
- manage the creation/deletion of Ethernet, ODU4-Client, ODU4-Network
and odu-connection to support the 100GE service over an OTN switch
- manage the new 100GE_S service-type in OtnDeviceRendererService
- propagate the service-type inside the renderer in order to have to
determine it only once at the highest renderer level
(RendererServiceOperations)
