Support for Placement Constraints in Granting with 3rd-party NFVO

Registered by Yuichi Ishihara on 2021-03-02

The grant operation is defined in ETSI NFV-SOL 003 v2.6.1 [1]
as a part of VNF Lifecycle Operation Granting interface.
As VNFM, Tacker implements grant operation defined in ETSI NFV-SOL 003 for 3rd party NFVO.

In this blueprint, the processing related to grant is expanded.
Specifically, the processing related to placement constraints [2] is newly implemented.
As a result, when interoperating with 3rd party NFVO, it is possible to deploy each VM in the VNF after setting the zone information based on the grant response from NFVO.

[2] Placement constraints such as affinity/anti-affinity rule that the VNFM may send to the NFVO in order to influence the resource placement decision. See [1] for details.
