    Functional regression test for evacuate with a target

    In I6ddcaaca37fc5387c2d2e9f51c67ea9e85acb5c5 we forgot to update the
    legacy filter properties dictionary so the requested target wasn't
    passed to the scheduler when evacuating.
    Adding a functional test for verifying the behaviour.

    NOTE(sbauza): The issue has been incendentally fixed in Pike by
    I434af8e4ad991ac114dd67d66797a562d16bafe2 so the regression test just
    verifies that the expected behaviour works.
    The Newton and Ocata backports will be slightly different from that one as we
    need to verify that host3 will be preferred eventually over host2.
