As the current Tacker only provides a limited number of sample VNFs,
this patch adds free5GC VNF samples for the operation verification,
which corresponds to ETSI NFV Plugtests Conformance testing.
This patch adds the following VNF packages.
- VNF
- VNF base
- ChangeExtConn
- Anti-Affinity
Implements: blueprint free5gc-vnf-samples
