This repo does not support Python 2 anymore, so we don't need
six for compatibility between Python2 and 3,
convert six usage to Python 3 code.
This changes urllib usage.
mock.patch usage in heat_dashboard/test/tests/api/test_heat.py
is modified to cope with the mix usage of urllib from python3 (in
heat-dashboard) and six.moves.urllib (in heatclient).
In the case of the mix usage, patching urllib.request.urlopen() only
does not work as urllib.request.urlopen() is not called after
resolving a lazy loading in six and the resolved object is
six.moves.urllib.request is called. The previous code depends on
the behavior in heatclient read_url_content() and the method should
be mocked instead. Considering this, mocking in api/test_heat.py
is modified to mock direct methods called in the heat-dashboard code.
