don't add token_format=PKI in keystone.conf any more, it is deprecated in Icehouse

[Adam Young]

Description of problem:
The "token_format" in the [signing] section of keystone.conf is deprecated. You get this message in keystone.log:

2014-02-06 10:09:00.942 31595 WARNING keystone.token.provider [-] keystone.conf [signing] token_format is deprecated in favor of keystone.conf [token] provider

Version-Release number of selected component (if applicable):
openstack-packstack-2013.2.1-0.29.dev956.fc20.noarch

How reproducible:
100%

Steps to Reproduce:
1. Make a packstack install of Icehouse
2. See the warning in keystone.log after the service starts

Actual results:
You get a warning not to use this setting any more

Expected results:
We shouldn't add this line to keystone.conf, starting from the Icehouse release

Is this still an issue? I'm on Icehouse and I cannot repro the deprecation warning on Icehouse 1:2014.1.2.1

This code was deprecated out in the icehouse branch so this issue is fixed.
