Description of problem:
Package python-openstackclient is missing python-appdirs Require:

[root@localhost ~]# openstack user list
Traceback (most recent call last):
  File "/usr/bin/openstack", line 6, in <module>
    from openstackclient.shell import main
  File "/usr/lib/python2.7/site-packages/openstackclient/shell.py", line 37, in <module>
    from os_client_config import config as cloud_config
  File "/usr/lib/python2.7/site-packages/os_client_config/__init__.py", line 15, in <module>
    from os_client_config.config import OpenStackConfig  # noqa
  File "/usr/lib/python2.7/site-packages/os_client_config/config.py", line 18, in <module>
    import appdirs
ImportError: No module named appdirs

Version-Release number of selected component (if applicable):
[root@localhost ~]# rpm -qa python-openstackclient
python-openstackclient-1.2.0-post24.fc21.noarch

Steps to Reproduce:
1. yum install python-openstackclient
2. openstack user list

Additional info:
This will probably need additional bug, but after installing python-appdirs manually I get following exception:

[root@localhost ~]# openstack user list
Traceback (most recent call last):
  File "/usr/bin/openstack", line 10, in <module>
    sys.exit(main())

    return OpenStackShell().run(argv)
