Set the default python to python3 except for the py27 environment. We
have to set that explicitly to override the new default.
As part of updating the pep8 job to run python 3 we need to remove the
use of the python 2 builtin unicode(). We can use six.text_type() to
produce the same result until we drop python 2 support.
