Add windows test

Overview

• Run tests on Windows in GitLab CI

  Add two new jobs tests windows and tests race windows to run the tests in a Windows environment.

  Example of failure in pipeline: https://gitlab.com/gitlab-org/ci-cd/custom-executor-drivers/autoscaler/pipelines/113197774

• Fix test on Windows with winRM enabled

  The test TestExecutor_Execute/port_availability_check_failure was failing on certain Windows machines that had winRM setup, becuase we had the winRM port hardcoded to 5985, and when testing the scenario of winRM responding it ends up responding since we hit a real winRM API instead of the mock one.

  The config is not available for the user to set at the moment we explicitly turn off the marshaling from toml

  Successful job: https://gitlab.com/steveazz/playground/-/jobs/426460735
