SDNC API

Upon receiving the alarm event, DCAE_Output_Event, an SDNC API is called to do the following:

Upda, te OTN service instance status.
Lookup for available IDL
Delete original domain services
Create new domain service accordingly
Associate the new IDL and domain services with the existing OTN service instance.
