    Delete server after resize test

    Explicitly deleting will prevent attempting to resize down an instance
    that was used for other resize tests. Every resize test will get its own
    server.

    Because there is now no potential to be resizing back and forth between
    flavor_ref and flavor_ref_alt we can do away with the code that tried to
    figure out what the direction should be. Resizes will now always be from
    flavor_ref to flavor_ref_alt, another protection against attempting to
    resize down.

    This does add extra work, deleting a server after each test and making a
    new one, however as it does away with resize direction ambiguity and
    happy accidental successes the performance hit is worth it.
