    [Compute]Make column content readable for both human and machine

    Currently, we use utils.format_dict(), utils.format_list(),
    utils.format_list_of_dicts to make column value can be easy to read by
    human, but osc support to format the CLI output into several format,
    like: json, shell, csv, yaml, most of these should be understand by
    program and code, so keeping the column content as the original value
    make sense, like {u'name': u'RuiChen'} than name='RuiChen'

    The patch include all compute commands.
