Keystone doc variable with DC set to com instead of org

[Sahdev Zala]

Just noticed that the keystone doc has,
  user_filter = (memberof=CN=openstack-users,OU=workgroups,DC=openstack,DC=com)
in the file keystone/doc/source/configuration.rst

Setting DC=org is ideal and consistent with other values.
