ca_certs=DISABLE must disable Python 2.7.9's new certificate verification

In Python <= 2.7.8 ca_certs=DISABLE works because
httplib.HTTPSConnection doesn't validate but
CertValidatingHTTPSConnection does. In 2.7.9 httplib.HTTPSConnection
must be told not to validate. SSL contexts aren't exposed to Python
code before 2.7.9 so CertValidatingHTTPSConnection is still needed for
backwards compatibility and _create_unverified_context support is
detected at runtime.
