neutron-rally-neutron fails with `NeutronTrunks.create_and_list_trunk_subports` in in any platform

[Boden R]

It appears the neutron-rally-neutron job is failing intermittently with:

2018-06-25 21:27:31.654 4361 ERROR rally.task.engine [-] Invalid Task: PluginNotFound: There is no plugin `NeutronTrunks.create_and_list_trunk_subports` in in any platform.

For example [1] (stable/queens).
It appears to have started happening around 6/22/2018 as per [2].

It is definitely different issue then reported in https://bugs.launchpad.net/neutron/+bug/1777506 but it is possible that https://review.openstack.org/578104 will fix this issue - let's check :)

[Slawek Kaplonski (slaweq)]

Looks like it impacts again all stable/queens patches. Other examples:

    Use rally 0.12.1 release for stable/queens branch.

    Rally does not have any alignment of own tags to OpenStack releases.
    In theory it should be possible to launch the latest Rally against
    old clouds.

    To follow the common processes and policy, Rally synchronized own
    dependencies (python-*client's and oslo.* libs) with g-r. It made a
    conflict between installed versions by stable/queens@devstack and
    rally itself.
    With Rally master branch it became an error (Rally's team is
    working on moving in-tree OpenStack plugins to the separate repository
    openstack/rally-openstack).
    Rally 0.12.1 is the latest release which doesn't contain a breaking
    change.

    Ideally, to avoid such issues in future, Rally devstack plugin and
    zuul job should install Rally in a virtual environment, but such
    change requires more time for investigation and implementation.

    So this patch is a quick workaround to avoid version conflict
    of python dependencies.

This issue was fixed in the openstack/neutron 12.0.4 release.
