Allow specifying specific versions of containerd for Kubernetes releases
and clarify recommendations and support policy.

These tests are launching containerd and pulling busybox there, while
other tests are using busybox from TestMain().
This commit shares busybox at least between TestRestartMonitor and
TestRestartMonitorWithOnFailurePolicy to reduce the chance of
throttling from ghcr.io.

Schema 1 has been substantially deprecated since circa. 2017 in favor of Schema 2 introduced in Docker 1.10 (Feb 2016)
and its successor OCI Image Spec v1, but we have not officially deprecated Schema 1.
One of the reasons was that Quay did not support Schema 2 so far, but it is reported that Quay has been
supporting Schema 2 since Feb 2020 (moby/buildkit issue 409).
This PR deprecates pulling Schema 1 images but the feature will not be removed before containerd 2.0.
Pushing Schema 1 images was never implemented in containerd (and its consumers such as BuildKit).
Docker/Moby already disabled pushing Schema 1 images in Docker 20.10 (moby/moby PR 41295),
but Docker/Moby has not yet disabled pulling Schema 1 as containerd has not yet deprecated Schema 1.
(See the comments in moby/moby PR 42300.)
Docker/Moby is expected to disable pulling Schema 1 images in future after this deprecation.

This test tends to fail under Cirrus CI + Vagrant. Skipping for now
since running the test on GitHub Actions would be suffice.

This patch adds support for a container annotation and two separate
pod annotations for controlling the blockio class of containers.
The container annotation can be used by a CRI client:
"io.kubernetes.cri.blockio-class"
Pod annotations specify the blockio class in the K8s pod spec level:
"blockio.resources.beta.kubernetes.io/pod"
(pod-wide default for all containers within)
"blockio.resources.beta.kubernetes.io/container.<container_name>"
(container-specific overrides)
Correspondingly, this patch adds support for --blockio-class and
--blockio-config-file to ctr, too.
This implementation follows the resource class annotation pattern
introduced in RDT and merged in commit 893701220.

While gogo isn't actually used, it is still referenced from .proto files
and its corresponding Go package is imported from the auto-generated
files.

If containerd crashes while creating a container the shim process stays alive and is never
cleaned up. Details are discussed in issue containerd/containerd#6860. This fixes the code
to cleanup such shim processes on containerd restart.

"uname -a" includes its hostname, which could be

This is unnecessary invalidating the cache.
