For Kata Containers, starting a privileged container will fail
if passing all host devices to container due to the permission
issue, like the `privileged_without_host_devices` for CRI service,
add a `privileged-without-host-devices` to `ctr run` command will
disable passing all host devices to containers.

Added new runc shim binary in integration testing.
The shim is named by io.containerd.runc-fp.v1, which allows us to use
additional OCI annotation `io.containerd.runtime.v2.shim.failpoint.*` to
setup shim task API's failpoint. Since the shim can be shared with
multiple container, like what kubernetes pod does, the failpoint will be
initialized during setup the shim server. So, the following the
container's OCI failpoint's annotation will not work.
This commit also updates the ctr tool that we can use `--annotation` to
specify annotations when run container. For example:
```bash
➜ ctr run -d --runtime runc-fp.v1 \
--annotation "io.containerd.runtime.v2.shim.failpoint.Kill=1*error(sorry)" \
docker.io/library/alpine:latest testing sleep 1d
➜ ctr t ls
TASK PID STATUS
testing 147304 RUNNING
➜ ctr t kill -s SIGKILL testing
ctr: sorry: unknown
➜ ctr t kill -s SIGKILL testing
➜ sudo ctr t ls
TASK PID STATUS
testing 147304 STOPPED
```
The runc-fp.v1 shim is based on core runc.v2. We can use it to inject
failpoint during testing complicated or big transcation API, like
kubernetes PodRunPodsandbox.

Currently, ctr import will use loose matching as defined by
platforms.Only(), meaning in the case of platform linux/amd64 as in
issue#6441, importing will also match linux/386 platform on the
image-to-be-imported's index. However, that image-to-be-imported may not
have both the linux/amd64 and linux/386 platform contents, resulting in
a failure to unpack the image. This change makes that check strict such
that the requested platform to import for is the only platform content
imported. Both ctr pull and ctr export will treat the platform option as
strict, so this change makes ctr import consistent with those.

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 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.

Go 1.15.7 contained a security fix for CVE-2021-3115, which allowed arbitrary
code to be executed at build time when using cgo on Windows. This issue also
affects Unix users who have “.” listed explicitly in their PATH and are running
“go get” outside of a module or with module mode disabled.
This issue is not limited to the go command itself, and can also affect binaries
that use `os.Command`, `os.LookPath`, etc.
From the related blogpost (ttps://blog.golang.org/path-security):
> Are your own programs affected?
>
> If you use exec.LookPath or exec.Command in your own programs, you only need to
> be concerned if you (or your users) run your program in a directory with untrusted
> contents. If so, then a subprocess could be started using an executable from dot
> instead of from a system directory. (Again, using an executable from dot happens
> always on Windows and only with uncommon PATH settings on Unix.)
>
> If you are concerned, then we’ve published the more restricted variant of os/exec
> as golang.org/x/sys/execabs. You can use it in your program by simply replacing
This patch replaces all uses of `os/exec` with `golang.org/x/sys/execabs`. While
some uses of `os/exec` should not be problematic (e.g. part of tests), it is
probably good to be consistent, in case code gets moved around.
