Information Structure allows just a single Application per ManagementDomain

[openBackhaul]

Problem in the Information Structure of the CDM:
The FD is identified by managementDomain.
The FCs inside are identified by deviceName.
If a second Application would be connected to the ManagementDomain

• the would be one Link to the LoadBalancer
• but 42,ooo FCs to the LogicalController.

=> There would either be two FCs that are identified by the same deviceName, or the individual FC wouldn't be linear, but tree shaped (ending at one LoadBalancer, but multiple Applications).

Obviously, there can't be two entries identified by the same ID in the list.
Tree shaped FCs (and Routes) would be very hard to validate and calculation of the operational state would be very complicated.

Added a lowerLevelForwardingDomain representing the Application that is connected to a ManagementDomain.
This solves the problem of ManagementPlaneTransportFCs being again uniquely identified by deviceName.
