https://github.com/openstack/octavia-tempest-plugin/commit/0a0f9b342a73c924ba9e7142878a2889ac2061aa broke it.
and https://github.com/openstack/octavia-tempest-plugin/commit/0a0f9b342a73c924ba9e7142878a2889ac2061aa#diff-b03119484154d807139512ef9393b286R28 -> adds a new import octavia_lib comes from https://github.com/openstack/octavia-lib which is not yet packaged in RDO.

Best solution pin the plugin in rdo at known commit and till then work on packaging the dependence in RDO.
Once package is available add a Requires in python-octavia-tests-tempest packages.
