Description of problem:

The pkg "python-six" is not installed when installing Swift without the proxy package (for example, on a storage-only node). Even when installing the proxy pkg, "python-six" is only installed due to the dependency to python-keystoneclient.

Version-Release number of selected component (if applicable):

9. Likely that this is also the case in earlier versions that make use of six.

How reproducible:

Always

Steps to Reproduce:
1. yum install openstack-swift
2. Execute "swift-ring-builder"

Actual results:

[vagrant@swiftproxy ~]$ swift-ring-builder
Traceback (most recent call last):
  File "/usr/bin/swift-ring-builder", line 20, in <module>
    from swift.cli.ringbuilder import main
  File "/usr/lib/python2.7/site-packages/swift/cli/ringbuilder.py", line 31, in <module>
    from six.moves import zip as izip
ImportError: No module named six.moves

Expected results:

No exception raised.
