Update httplib to use python3 compatible code

This code has zero impact on python2.
ex:
from six.moves import http_client as httplib
print httplib
<module 'httplib' from '/usr/lib64/python2.7/httplib.pyc'>

This code will not be testable in python3 until all other
incompatible components are updated.
