Open Stack

> Jay, fair enough. ive peeped the memcache stuff in nova, and see that its used for caching metadata and a few other things. i agree this should be a common thing at this point. ill look into getting cache code into openstack common and replace the keystone auth middleware & the nova memcache stuff with it, especially if no one has objections. BP to follow for openstack common stuffs.

please keep in mind that the auth_token middleware has been designed
to be run "as is" make it easy to be dropped in an environment with no
need for dependences.
