Over the time the catalog is clogged with VFs and services that are no longer needed. A function to support deleting such VFs and services could help to clean up the catalog. We want to support:

1. Delete a single VF or service.
2. Batch delete multiple VFs and services.

Need to identify the dependency of a VF/service before allowing delete operation. For now, we only allow the following cases:

• VF: If an VF is not used by any service, then it can be deleted. Note that a VF can be used by a service even if it is not tested by the tester. 
• Service: If a service is not distributed, then it can be deleted. If a service is referenced by a allotted resource or proxy service, then there is dependency and it cannot be deleted.
• Nested delete is beyond the scope.
• Show the user of dependencies in case delete is not allowed.

UI design is to be added. SDC code need to be studied to understand what's under the hood.

Archiving/restoring is already implemented in AT&T and the code has been contributed to SDC R3.  It uses the same set of constraints as 'Delete'.
