1，using a service template to describe a VDU, and using the
substitution mapping feature to abstract the VDU to be a new VDU
node type.
2, Defining virtualComputeDesc and virtualStorageDesc in the
DSL_definitions section in a VNFD service template, so multiple
VDUs can reference the same virtualComputeDesc or
virtualStorageDesc.
3, Defining swImageDesc as a artifact in a VDU.
Thank you!
