    Fix target_helper config for >= Wallaby

    Starting with the release of Wallaby, the 'tgtadm' package is
    now the default target helper, which doesn't work for cinder-lvm.
    As such, we need to explicitly set the new package to 'lioadm'.

    (cherry-pick modified to disable py36 unit tests as they are not
    needed at yoga, and break as the psycopg2-binary wheel has
    been removed from PyPi, and the tools to build the wheel are not
    in the repo; it's less work to just fake the result on py36 than
    to support it, and it's less CI time as well).
