So, for this to remain RC for nova I need a list of patches that need
review. If we don't have that basically now, then we're going to need to
drop this from rc1.

(That doesn't mean its important, just that I don't think we can hold
rc1 waiting for it).

  Some server-side 'SSL' communication fails to check certificates (use

Bug description:
  Grant Murphy from Red Hat reported usage of httplib.HTTPSConnection
  objects. In Python 2.x those do not perform CA checks so client
  connections are vulnerable to MiM attacks.

  """
  The following files use httplib.HTTPSConnection :
  keystone/middleware/s3_token.py
  keystone/middleware/ec2_token.py
  keystone/common/bufferedhttp.py
  vendor/python-keystoneclient-master/keystoneclient/middleware/auth_token.py

  AFAICT HTTPSConnection does not validate server certificates and
  should be avoided. This is fixed in Python 3, however in 2.X no
  validation occurs. I suspect this is also applicable to most OpenStack
  modules that make HTTPS client calls.

  Similar problems were found in ovirt:
  https://bugzilla.redhat.com/show_bug.cgi?id=851672 (CVE-2012-3533)
