Clean up py35 env in tox.ini.

This patch enables the py35 job in tox.ini to run using ostestr.
It also fixes a bytes encoding issue in the 'test_wsgi' functional
test to make progress towards the community goal of enabling
python3.5. Two other functional tests remain disabled and will need
to be addressed in a later patch in order to fully complete the
community goal - 'test_ssl' and 'test_reload'. These tests fail
due to SSL handshake not working in python3.5 when using self-signed
certificate and authority.
