Remove Python 3.5 tests on GitHub (#1002)
Remove Python 3.5 tests on GitHub (#1002)

Python 3.5 is EOL this Sept, and the default system python for 3.5 is
Ubuntu 16.04 which has EOLed. For that it makes sense to remove the
test against Ubuntu 16.04 on GitHub.

This will help reduce GitHub Actions burden.

Note we still releases pyhton 3.5 wheel packages (until TF drops python3.5 support).
