Currently, the cri-integration tests do not work on Windows due to various reasons. One of the reasons is because all the tests are using Linux-specific images. This commit refactors the image pulling / usage in the cri-integration tests, making it easier to update, and easier to configure the a custom registry to pull those images from. For Windows runs, custom registries can be created, which will also contain Windows images, and the cri-integration tests can be configured to use those registries by specifying the "--image-list" argument, a TOML file which will contain an alternative mapping of the default images.
