The urllib, urllib2 and urlparse modules of Python 2 were reorganized into a new urllib namespace on Python 3. Replace urllib, urllib2 and urlparse imports with six.moves.urllib to make the modified code compatible with Python 2 and Python 3. The initial patch was generated by the urllib operation of the sixer tool on: bin/* swift/ test/. Change-Id: I61a8c7fb7972eabc7da8dad3b3d34bceee5c5d93
