Only test cases using local NFVO are included in the FT of the
current v2 API.
This patch provides a new FT job for the v2 API to test seperated
NFVO scenarios.
1. The split NFVO in this patch is to be simulated using code.
2. This patch will merge the fake_grant_server.py of v1 as a common
fake_grant_server for users to test manually.
