There are still some left, but the `modification_check` test fails. Some are still in `tools`, and they can probably be removed as well. `with_statement` was introduced officially in Python 2.5, so there's really old stuff in the code base.
As discussed in #7539, we need proper tests of the Windows installer itself in order to variety that all the logic contained in a production-grade runtime of Certbot on Windows is correctly setup by each version of the installer, and so for a variety of Windows OSes.
This PR handles this requirement. The new `windows_installer_integration_tests` module in `certbot-ci` will:
* run the given Windows installer
* check that Certbot is properly installed and working
* check that the scheduled renew task is set up
* check that the scheduled task actually launch the Certbot renew logic
The Windows nightly tests are updated accordingly, in order to have the tests run on Windows Server 2012R2, 2016 and 2019.
These tests will evolve as we add more logic on the installer.
* Configure an integration test testing the windows installer
* Write the test module
* Configurable installer path, prepare azure pipelines
* Fix option
* Update test_main.py
* Add confirmation for this destructive test
* Use regex to validate certbot --version output
* Explicit dependency on a log output
* Use an exception to ask confirmation
* Use --allow-persistent-changes
