This is blocked on #8149 having been resolved and included in a release.

Once that happens though, I think we should drop Python 3.5 support by

• Remove Python 3.5 from the classifiers in setup.py for each package.
• Update the python_requires value in each packages setup.py file to exclude Python 3.5.
• Update any Azure tests using Python 3.5 to a newer version of Python or delete the test entirely.
• Remove the deprecation warnings added to fix Deprecate Python 3.5 support #8149
• Update any files such as contributing.rst or install.rst to not claim support for Python 3.5.
