Function starts a job that makes predictions to input data with a given model.

    Parameters
    ----------
    input - dataset object with input urls and other parameters
    fitmodel_url - model created in fit phase
    save_results - save results to ddfs
    show - show info about job execution

    Returns
    -------
    Urls with predictions on ddfs
