Distro tempest failure: octavia_tempest_plugin.tests.scenario.v2.test_traffic_ops.TrafficOperationsScenarioTest

[coreycb]

In this case it is reproduced with 'tox -e func-target focal-ussuri' but can likely be reproduced on (m)any releases.

Info from Chris M. He says this can be resolved by going back from master to the released version (as a workaround). The problem is the admin user we get doesn't have system scope. It is probably the case that we can resolve it by updating how we get our overcloud admin credentials
