cannot import name 'cached_property' from 'werkzeug'

[bill-uncultured]

werkzeug just released 1.0.0, and the deprecated werkzeug.cached_property has been removed in favor of werkzeug.utils.cached_property.

This was addressed in October by pull request # 141, but it seems like it failed testing because the old python 3.3 and 2.6 couldn't be downloaded.

/usr/lib/python3.7/site-packages/flask_testing/__init__.py:13: in <module>
    from .utils import TestCase, LiveServerTestCase
/usr/lib/python3.7/site-packages/flask_testing/utils.py:35: in <module>
    from werkzeug import cached_property
E   ImportError: cannot import name 'cached_property' from 'werkzeug' (/usr/lib/python3.7/site-packages/werkzeug/__init__.py)

Same issue as: noirbizarre/flask-restplus#777

The proposed temporary solution is to pin Werkzeug==0.16.1 until a proper fix is put in place.

I have created a fix for this #144

but CI infrastructure is not working

Another fix would be to edit the flask_testing/utils.py on line 35:
Use
from werkzeug.utils import cached_property
instead of
from werkzeug import cached_property

There's already a (closed) MR: #146

And an open one: #145

Edit: #145 has been merged

Any updates regarding CI?
