In python=<2.6, collections.Mapping inherits from
collections.Sized, collections.Iterable, and collections.Container
which are also subclasses of object.

Title:
  cfg: unneeded multiple inheritance

Status in openstack-common:
  In Progress

Bug description:
  From Monsyne Dragon in https://review.openstack.org/3729

    File nova/openstack/common/cfg.py
    Line 696: class ConfigOpts(collections.Mapping, object):
    I don't think we really need to multiply inherit from 'object' here. 
    esp. since collections.Mapping already inherits from object.

    While this doesn't affect anything atm, this kind of diamond inheritance may lead to some rather non-intuitive behavior if  
    someone subclasses ConfigOpts in the future
