python-keystoneclient does not depend on python-requeusts>=0.8.8

python-keystoneclient-1:0.2.3-0ubuntu1~cloud0 requies python-requeusts but does not force an upgrade of python-requests when the python-keystoneclient package is upgraded (i.e. from folsom to grizzly using the grizzly cloud-archive packages)

Upgrading python-requests to 1.1.0-1~cloud0 from cloud-archive resolves this problem.
