    Make compute rpcapi version calculation check all cells

    For top-level services, the compute rpcapi module needs to check for the
    minimum version of nova-compute in all cells in order to function
    properly during an upgrade. This moves that module to use the all-cells
    variant of this routine in the case where [api_database]/connection is
    set.
