Yasufumi Ogawa a3377de871 Drop most of six importings
This update is to drop six, and also Python2 support. However, only
`tacker/test/common/helpers.py` which defines a set of functions for
Python2 is remained because `compact_byte()` is called from several test
classes. Although it'is not so quite hard to drop, better to be done in
another patch because so many changes shouldn't be included in a update.

Here is a summary of changes.

* Remove all six importing other than `helpers.py`.

* Revise the order of importing modules becaseu it's checked strictly
  more in the recent pep8 test.

* For the update, it removes a test `test_json_with_utf()` defined in
  `tacker/tests/unit/test_wsgi.py` because it's required only for Python2
  and can be skipped for Python3, so no need to keep anymore.

* Remove six from `requirements.txt` and `lower-constraints.txt`.

Partial-bug: #1778644
