proliantutils does not work with urllib3 1.9.1

When using self signed certificate on iLOs of HP Proliant Servers with urllib3, the following error is seen:

>>> from proliantutils.ilo import client
>>> ilo_client = client.IloClient('your-test-server.local', 'Administrator', 'password')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/stack/venvs/ironic/local/lib/python2.7/site-packages/proliantutils/ilo/client.py", line 47, in __init__
    self.model = self.ribcl.get_product_name()
  File "/opt/stack/venvs/ironic/local/lib/python2.7/site-packages/proliantutils/ilo/ribcl.py", line 256, in get_product_name

    d = self._request_ilo(xml)
  File "/opt/stack/venvs/ironic/local/lib/python2.7/site-packages/proliantutils/ilo/ribcl.py", line 76, in _request_ilo
    raise exception.IloConnectionError(e)
proliantutils.exception.IloConnectionError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)>

After updating the ribcl.py with the following code, it works.
import urllib2
import ssl

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

urllib2.urlopen("https://your-test-server.local", context=ctx)
