Even though there was a py36 test enabled in the gate, the tox.ini
configuration was not actually invoking the unit tests. This
change sets up the environment to allow tests to run.
As a result, a number of Python3 errors are uncovered and fixed.
Notably:
Python 3 does not have contextlib.nested, so reformatting using ,
file() is not in Python 3, so use io.open() instead
Use six.assertCountEqual(self, in tests
safe_decode:
subprocess.check_output returns in byte encoding, while default text
type str. safe_decode does the right thing by making sure string are not
bytes in python2 and python3
No ascci encoding:
python3 defaults to UTF-8 encoding, which is merely an extension to
ascii (default for python2).
test_json_plugin.py:
the file being opened in binary(wb) mode so python is expecting the
string in bytes.
Some of the refactoring should be revisited after we drop Python 2
support.
