I noticed AdaptInfo missing test cases. I think this
func a bit important to test since we use this func
in other packages like content, store (walking), etc.

This change splits the definition of pkg/cri/os.ResolveSymbolicLink by
platform (windows/!windows), and switches to an alternate implementation
for Windows. This aims to fix the issue described in containerd/containerd#5405.
The previous implementation which just called filepath.EvalSymlinks has
historically had issues on Windows. One of these issues we were able to
fix in Go, but EvalSymlinks's behavior is not well specified on
Windows, and there could easily be more issues in the future, so it
seems prudent to move to a separate implementation for Windows.
The new implementation uses the Windows GetFinalPathNameByHandle API,
which takes a handle to an open file or directory and some flags, and
returns the "real" name for the object. See comments in the code for
details on the implementation.
I have tested this change with a variety of mounts and everything seems
to work as expected. Functions that make incorrect assumptions on what a
Windows path can look like may have some trouble with the \\?\ path
syntax. For instance EvalSymlinks fails when given a \\?\UNC\ path. For
this reason, the resolvePath implementation modifies the returned path
to translate to the more common form (\\?\UNC\server\share ->
\\server\share).

This forces vendoring to only take dependencies of this repository to
be taken into account, effectively cutting the circular dependency (for
the vendored code), and to prevent depending on transitive dependencies
coming from older versions of containerd.
go mod does not allow using the main module as a local "replace" rule using
a path; see golang/go#45492 and golang/go#34417, so instead, an empty module
is used.
One change observed is that older versions containerd depended on an older
version of imgcrypt that had an "indirect" dependency on more current versions
of gopkg.in/yaml.v2 and prometheus/procfs.
For those, a temporary "indirect" dependency was added, until prometheus/client_golang
and kubernetes are updated.
from go mod graph (before):
github.com/containerd/imgcrypt@v1.0.4-0.20210301171431-0ae5c75f59ba gopkg.in/yaml.v2@v2.4.0
github.com/containerd/imgcrypt@v1.0.4-0.20210301171431-0ae5c75f59ba github.com/prometheus/procfs@v0.6.0
For some reason, some older versions of containerd are still taken into account,
causing satori/go.uuid to be added as "indirect" dependency, likely because some
modules have this dependency in their go.sum. This should likely disappear once
those plugins are updated to contain a current version of containerd.

We can check that the reported containers stats are not lower than it should
by using the resource-consumer image. This image contains stress / testlimit.exe
which can consume a specified amount of memory.

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.

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.
