    BigSwitch: Add SSL Certificate Validation
    
    This patch adds the option to use SSL certificate
    validation on the backend controller using SSH-style
    sticky authentication, individual trusted
    certificates, and/or certificate authorities.
    Also adds caching of connections to deal with
    increased overhead of TLS/SSL handshake.
    
    Default is now sticky-style enforcement.
    
    Partial-Bug: 1188189
    Implements: blueprint bsn-certificate-enforcement

Title:
  Some server-side 'SSL' communication fails to check certificates (use
  of HTTPSConnection)

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:
