We don't specify any regex for this job, so it runs some tests.
They only include test_network_basic_ops, which does not check that
multitenancy is in effect. We have a test for it in ironic-tempest-plugin,
but it does not run anywhere. There is a neutron test for the same,
but it's not a smoke test and it has been skipped for quite some time.
This change switches this job to the run the following tests:
* all ironic tests (that are not skipped for any reason)
* multinode tests from Nova
Unfortunately, this patch uncovers that we don't run any tests for
network attach/detach in practice. The devstack plugin has to be updated
first to support more than one port per node. A TODO is left in the playbook.
