    Only delete workflows with the tripleo-common-managed tag

    The new workflow tag allows us to detect tripleo-common workflows. It is
    safe to delete and reload these. Workflows that come from other places
    shouldn't be removed.

    There is some upgrade logic here that handles the O -> P upgrade, as on
    the first run the workflows will not have the tripleo-common-managed
    tag. If the tag isn't found, we revert to the current behaviour and then
    on future undercloud installations this wont be a problem.

    The new test is a duplication of a previous test but with multiple
    workflows that have tripleo in the name. Only the one with the tag is
    deleted.
