TypeError: 'NoneType' object does not support item assignment with latest os-client-config

[Javier Peña]

During tests with the current python-openstackclient master, we get the following error:

ERROR: openstackclient.shell Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/openstackclient/shell.py", line 152, in run
    return super(OpenStackShell, self).run(argv)
  File "/usr/lib/python2.7/site-packages/cliff/app.py", line 224, in run
    self.initialize_app(remainder)
  File "/usr/lib/python2.7/site-packages/openstackclient/shell.py", line 245, in initialize_app
    cloud_config.set_default('auth_type', 'osc_password')
  File "/usr/lib/python2.7/site-packages/os_client_config/config.py", line 67, in set_default
    defaults._defaults[key] = value
TypeError: 'NoneType' object does not support item assignment

This is apparently caused by commit 50f05448982b5fafd9d9a7783b639dd145090a0d to os-client-config, which
removed the default values in the _defaults dict. This makes any call to cloud_config.set_default() before initializing the dict
fail.

I have proposed https://review.openstack.org/198788 with a fix.

    Fix the way auth_type default value is overriden

    Commit 50f05448982b5fafd9d9a7783b639dd145090a0d to os-client-config
    removed the default values in the _defaults dict. This makes any
    call to cloud_config.set_default() before initializing the dict
    fail.

    The fix changes the way the auth_type default is overriden, by
    doing it when cloud_config.OpenStackConfig() is executed.
