Schema 1 (`application/vnd.docker.distribution.manifest.v1+prettyjws`) has been
officially deprecated since containerd v1.7 (PR 6884).
We have planned to remove the support for Schema 1 in containerd v2.0, but this
removal may still surprise some users.
So, in containerd v2.0 we will just disable it by default.
The support for Schema 1 can be still enabled by setting an environment variable
`CONTAINERD_ENABLE_DEPRECATED_PULL_SCHEMA_1_IMAGE=1`, however, this workaround
will be completely removed in containerd v2.1.
Schema 2 was introduced in Docker 1.10 (Feb 2016), so most users should
have been already using Schema 2 or OCI.

Most of the tests creating and using Pod Sandboxes in the same way. We can create
a common function that will do that for us, so we can have less duplicated code,
and make it easier to add new tests in the future.

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.
Previous commits refactored the image pulling / usage in the cri-integration tests,
making it easier to update, and easier to configure a custom registry to pull images
with Windows support.
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 "--repo-list" argument, a YAML file which will contain an alternative
mapping of the default registries. This is similar to how E2E tests are handled for
Windows runs in Kubernetes.
Some of the tests are Skipped, as they do not pass yet on Windows.
Windows does not collect inodes used stats, thus, the tests that were expecting non-zero
inodes stats were failing.

Most of the tests are pulling and deleting the same test images, which
can be quite inefficient, especially on Windows nodes, where the images
are larger than the Linux ones (a nanoserver Container image is ~250MB
in size). We can instead pull them only once, and reuse them. This will
reduce the test run time on Windows considerably.
Additionally, some of the test images are currently hosted on dockerhub
(busybox image), which has introduced image ratelimiting in November 2020,
which means that test runners could potentially hit that limit faster with
the current implementation. This will reduce that risk.
Some tests are specifically deleting images, so we always have to ensure
that they are pulled.
