Fixes#8071 and fixes https://github.com/certbot/certbot/issues/8110.
This PR migrates every job from Travis in Azure Pipeline.
This PR essentially converts the Travis jobs into Azure Pipeline with a complete iso-fonctionality (or I made a mistake). The jobs are added in the relevant existing pipelines (`main`, `nightly`, `advanced-test`, `release`). A global refactoring thanks to the templating system is done to reduce greatly the verbosity of the pipeline descriptions.
A specific feature (not present in Travis) is added: the stage `On_Failure`. Using directly the Mattermost API, it allows to notify pipeline failure in a Mattermost channel with a link to the failed pipelines without the need to authenticate to Microsoft.
See https://github.com/certbot/certbot/pull/8098#issuecomment-649873641 for the post merge actions to do at the end of this work.
After #6485 and #6435, it appears that there is no good reason to not fail fast when test, cover or linting scripts are executed.
This PR ensures to fail fast by invoking commands throught subprocess.check_call instead of subprocess.call, and by removing the handling of non-zero exit code at the end of theses scripts.
As now coverage on Windows is executed with thresholds, I added specific thresholds for this platform. Because some portions of code that are done for Unix platform will not be executed on Windows.
Note that coverage reports from Travis and AppVeyor are accumulated on Codecov. So if a file is covered up to 50 % on Linux, and all other parts are covered on Windows, then coverage is 100 % for Codecov.
Note: that PR also fixes the ability of coverage tests to fail if thresholds are exceeded.
* Use check_call to fail fast in all scripts related to tests/lint/coverage/deploy
* Make specific coverage threshold for windows
Certbot relies heavily on bash scripts to deploy a development environment and to execute tests. This is fine for Linux systems, including Travis, but problematic for Windows machines.
This PR converts all theses scripts into Python, to make them platform independant.
As a consequence, tox-win.ini is not needed anymore, and tox can be run indifferently on Windows or on Linux using a common tox.ini. AppVeyor is updated accordingly to execute tests for acme, certbot and all dns plugins. Other tests are not executed as they are for Docker, unsupported Apache/Nginx/Postfix plugins (for now) or not relevant for Windows (explicit Linux distribution tests or pylint).
Another PR will be done on certbot website to update how a dev environment can be set up.
