Documentation    Test cases for ETSI NFVO NS Lifecycle Management Operations
...    Create and Delete tests are synchronous
...    Instantiate and Terminate tests are asynchronous, test status checked through request to NS_LCM_OP_OCCs endpoint
...    Note, relies on:
...      -Network Service package being onboarded in etsi_package_onboarding_tests
