Title:
  StackTrace on 2012.1.4 middleware when storing token in memcache with
  SWIFT 1.7.4

Bug description:
  when integrating Keystone 2012.1.4 with SWIFT, and swift-proxy is configured to cache tokens in memcache, we get a response "500 internal server error" from swift because keystone.middleware.auth_token stacktraces with :
  "TypeError: %d format: a number is required, not str" in two situations.

  #1 when a new token wants to be cached
  #2 when an invalid ( non existent or expired ) token is cached

  For the #1 & #2 cases, we patched /usr/local/lib/python2.7/dist-
  packages/keystone-2012.1.[VERS]-py2.7.egg/keystone/middleware/auth_token.py
  in the line 151 and replaced :

  self.token_cache_time = conf.get('token_cache_time', 300)
  with
  self.token_cache_time = int(conf.get('token_cache_time', 300))

  We think its a big and anoying bug when you need this feature from keystone ( most of serious SWIFT implementations )
  Thanks !!
