    Add support, in new placement microversion 1.16, for a ``limit`` query
    parameter when making a ``GET /allocation_candidates`` request. The
    parameter accepts an integer value, `N`, which limits the number of
    candidates returned. A new configuration item
    ``[placement]/randomize_allocation_candidates``, defaulting to `False`,
    controls how the limited results are chosen. If `True`, a random sampling
    of the entire result set is taken, otherwise the first N results are
    returned.
