    Fix version negotiation

    When the python client catch a 406 (Not Acceptable) error talking to
    an older version of the Ironic server the client will try to negotiate
    and fall back to the minimum supported version. Before the code was
    determining the minimum version by using the builtin min() method with
    strings but the result doesn't always come correct by doing it, e.g:

    In [1]: min('1.10', '1.6')
    Out[1]: '1.10'

    In [2]: min('1.9', '1.6')
    Out[2]: '1.6'

    This patch fix this problem with the version negotiation.
