Sync py3kcompat from oslo-incubator

Python3 reorganized the standard library and moved several
functions to different modules and combined modules. Six
provides a consistent interface to the module through
six.moves

However urllib/urlparse is not covered by six.moves so
py3kcompat adds python2/python3 compatibility layer for
urllib/urlparse.

python3: Use from future import unicode_literals

use  "from future import unicode_literals" instead of u""

To the road to Python3, a possible next step would be to use the from __future__ import unicode_literals
and remove the u'' prefixes, as it is not supported in Python3.
