    Make service all-cells min version helper use scatter-gather

    This makes the Service get_minimum_version_all_cells() helper use the parallel
    scatter-gather utilities to make the determination. It also adds fault handling
    for cases where a cell fails to respond, and an option to ignore or raise in
    that situation.
